How to get GA traffic when using AIG, ST, etc. - UPDATED

Thank you for this! Have it working well with AIG. I’m wondering what the specific limitation is to the number of ai flightplan legs that can be included with a mod that you mention in the instructions? Also, when I decompile the mod bgl file with AIFP, the aircraft list seems to include duplicate references the UI instances of the Cessna 172 (e.g. [FLTSIM.0], not the AI Traffic version ([FLTSIM.1 to FLTSIM.4]) instances from the aircraft.cfg. Is that just by choice or does it have to do at all with how the MSFS 2020 ai system ultimately works? I noticed that the original bgl did the same thing.
