Separate textures for shoes and trousers?

[Banjaxx]

Is there a way to use separate textures for the lowr_ ped models, the ones where the shoes and trousers are welded together?
I've modeled a pair of adidas gazelles and got them in game, but the game uses the original lowr_diff_020_a_uni.dds on both the trousers and the shoes.

The gazekke shoe texture shows on the model in OpenIV, but not in game.

I just got back into modelling and I have a lot of stuff I'd like use in GTA and share with the community.
