Question about pushing info from sub family to parent family

As the title suggests, I’m trying to push information from one of my sub families…

…to the parent family.

The script that I have now was able to successfully able to filter out the information I wanted, but I’m having trouble telling it where to push the info.

I believe the missing steps area as follows but I just can’t figure out how to do it.

Box Element values -> Find the boxes associated with it -> Find the different parts in the family -> look at just the pitchforks -> push the value to the pitchfork parameter

Help me internet. You’re my only hope.

P.S. The _T,_M,_B parts shown are my notation for which box the information is in. I.E. _T = top box, _M = Middle box, _B = bottom box. This is why there’s three variables in the parent family.

P.P.S. If I can pull this off it means then it means that I can do about 7 weeks (probably considerably more) worth of work in about 5 minutes. This isn’t really relevant to the question. I just thought it was really cool and wanted to brag about it.

Update: I figured out I can do this to filter the boxes (step 1)

I figured it out: I needed the FamilyInstance.SuperComponent from the Clockwork Package. Here’s the finished script for reference
