add inset graph in sas? - sas

Question

I'm wondering if there's a way to add an inset graph in another graph in SAS. I see quite a bit of stuff about adding text insets into a figure, but nothing about a graph. I am making scatterplots with, for example, leaf mass on the x-axis, and leaf area on the y. The slope of the line tells me the ratio of these two quantities, which is specific leaf area. This is also important, so I want to be able to show that, as well. But since its not new information (relative to the scatterplots), I don't want to make another figure since it will basically show the same thing, just in different ways. But if I had it as an inset, that would be okay.
I use SAS 9.4 at school and SAS university edition at home. Here's the code I have for the scatterplot:
proc template; define statgraph Graph;
dynamic _MASS_PER_LEAF _SA_PER_LEAF _GROUP _LT_MASS_PER_LEAF _LT_SA_PER_LEAF _GROUP2;
begingraph / designwidth=500 designheight=819 attrpriority=none DataSymbols=(circle x circle x circle x) DataContrastColors=(CX0000FF CX0000FF CXCC0033 CXCC0033 CX639A21 CX639A21)

regressionplot x = mass_per_leaf y = sa_per_leaf / group = group;

endlayout;

endlayout;

columnaxis / label=('Average mass per leaf (g)');
endcolumnaxes;
endlayout;
endgraph;
end;
run;
proc sgrender data=WORK.CALCIUM template=Graph;

Thank you for any help!
