Attempt to modify the standard RMG.

Understood. It's a shame that it's so complicated to implement, especially if custom executables or DLLs are required. Okay, I'll create a setting in RefTables for myself, using non-interchangeable sums for objects, so I can get the objects I need in specific zones, and then I'll write templates for them. Let's see what comes of it.
Thank you very much for your help.
