I FIGURED IT OUT! FINALLY HELL YEAH!
so basically i had to create a master material out of a random dummy texture then with that material i changed the texture sample with a texturesample2d param thing then i connected everything like i would normally like connecting alpha to opacity mask and such then i created an instanced material out of that one and checked the texture parameter and stuff and then when importing i selected PARAM instead of no override on all sections and it imported with alpha to opacity 2 sided and all
