How to interrupt a page-sequence to insert another page-sequence - xslt

Question

Via xsl:for-each-group I group my data with a property pagemaster. For this group I assign the page-sequence in the attribute pagemaster. Then the template is called for each element in this group.
Now to my question: is it somehow possible that I leave the current page-sequence in the for-each loop to insert another page-sequence and then continue with the previous one?
As an example, let's assume that all elements in the group should be rendered on blue pages, but if an element has a certain attribute, a red page will be inserted at this place.
My code section looks like this:
.
<!-- master-set defined here -->
.
</fo:layout-master-set>
<xsl:for-each-group select=".//reportelements/*[pagemaster != '']" group-adjacent="pagemaster">
<fo:page-sequence master-reference="{current-grouping-key()}">
<!-- Static-Content per pagemaster Group -->
<xsl:call-template name="STATIC-CONTENT">
<xsl:with-param name="pageMaster" select="current-grouping-key()" />
</xsl:call-template>
<fo:flow flow-name="xsl-region-body">
<xsl:for-each select="current-group()">
<!-- Here, for example, i would like to check if the current element (.)
is from type "section" and the attribute "hastoc" is true.
If yes the current page sequence should be interrupted and a new page-sequence
should be inserted on which the table of contents is rendered. -->
<xsl:apply-templates select="."/>
</xsl:for-each>
</fo:flow>
</fo:page-sequence>
</xsl:for-each-group>
</fo:root>
</xsl:template>
<xsl:template name="STATIC-CONTENT">
<xsl:param name="pageMaster" />
<xsl:if test="$pageMaster = 'TITLEPAGE'">
<fo:static-content flow-name="xsl-region-after">
<fo:block text-align="right">
<fo:external-graphic src="url(file:C\Logo.pdf)" content-width="6cm" />
</fo:block>
</fo:static-content>
</xsl:if>
</xsl:template>
Xml Code looks like
<?xml version="1.0" encoding="utf-8"?>
<root>
<report>
<layout>report.xsl</layout>
<namecontent>Report</namecontent>
<reportelements>
<section>
<layout>section_normal</layout>
<pagemaster></pagemaster>
<titlecontent>Vorspann</titlecontent>
<hastoc>false</hastoc>
<reportelements>
<picture>
<layout>picture_title</layout>
<pagemaster>TITLEPAGE</pagemaster>
<titlecontent>Titelpicture</titlecontent>
<reportelements />
<path>files\Titelpicture213124.Jpeg</path>
</picture>
<section>
<layout>section_leader.xsl</layout>
<pagemaster>DIN-A4-HEADER-ODD-EVEN</pagemaster>
<titlecontent>Profil</titlecontent>
<hastoc>true</hastoc>
<reportelements>
<paragraph>
<layout>paragraph_leader.xsl</layout>
<pagemaster>DIN-A4-HEADER-ODD-EVEN</pagemaster>
<titlecontent>p1</titlecontent>
<reportelements />
<textcontent>paragraph_leader 1 text</textcontent>
</paragraph>
<paragraph>
<layout>paragraph_leader.xsl</layout>
<pagemaster>DIN-A4-HEADER-ODD-EVEN</pagemaster>
<titlecontent>p2</titlecontent>
<reportelements />
<textcontent>paragraph_leader 2 text</textcontent>
</paragraph>
