Importing Disorganized Tags/Direct Tag Import

Is there any way to import tags in a more specific way than just a .csv/.json etc? I need to add a bunch of individual tags from a UDT inside the PLC and the individual tag names have absolutely no commonality or structure besides their hierarchy, which doesn't get translated to an export file. Is there any way to more directly access the tags from PLC code, specifically Logix designer?

Have you tried my alternate driver's JSON files? (Generated UDTs and tags from Logix browse information.)

If you avoid the "Compact" forms, the rest should be supported by the IA driver at runtime.

With that, you can make just one Ignition tag (udt instance) for that entire UDT in the PLC.
