[Need help] Create SP28 recolors without S4S update

I try to be patient until Sims4Studio gets its updates for the last couple of Kits, especially for the "modern menswear" Kit, so I don't bother the devs with "wHeN uPdAte?!?!?!111" you know. But now I struggle a bit. I decided to try it myself because they aren't any gameplay mechanics (I think) to prevent me just to get the "Modern menswear" meshes to work with.

I searched many days for a tutorial on how to extract files from the game without an updated S4S and I've found this tutorial here on the forum: How to extract files using S4S

But now here's my problem: I tried to extract files from the SP28 fullbuild package ... I was able to open it. In the "Warehouse" tag I was able to see the different CAS items with meshes (or parts of them) and texture files. I know I have to export the files I want to use now. But I don't know which parts belong together, especially for "SimInfo" or "Geometry" files.

My question is.../Where I need help...
Is there a way to filter all files by ... like a group as how they belong together so I won't miss exporting a file?
In case it's not possible I would be glad, too, if someone tells me so I won't keep on trying (and have to accept to wait for the update).

Thanks for everone who's willing to help here!
