how to merge two Add Column codes in same step? - powerbi

Question

I have the code below that
Searches the concatenation of the numeric parts in column STR of table Source within column VAL2 of table Codes. For example, for string abc.sec712.fir001.wpqdata, looks for 712001 in column VAL2. (CustomOUT1)
Searches the best match for values in column NUM of table Source within column VAL1 of table Codes. (Step `CustomOUT2)
These two steps are done separated using Table.AddColumn() in step CustomOUT1 and CustomOUT2.
Since both steps are using Table.AddColumn(), I'd like to join the logic of both steps in a single Table.AddColumn() step.
How can I do this?

....
CustomOUT2 = Table.AddColumn(

each
if [NUM] = "" then

...
then right click and remove column OUT1
