New to Printing, Started with Bambu P1S but...

So I'm enjoying finding files to download and print but it feels like Bambu is lacking on some aspects and then gatekeeping those.

Example: Why can't I import a .3mf with texture from another splitter? And since I can't, why isn't there a way to add texture to a model in Bambu Studio? I got the AMS because I'm not the most artistic and don't want to paint my prints. This option would make a huge difference. Out of the box, the printer is amazing but the tools to design, edit and adjust files in the Studio is severely lacking.
