Blender Materials to Bambu Materials

[psdwizzard]

I'm thinking about getting a Bambu printer and I have a lot of STLs that I've already designed from back when I ran my Patreon. I want to upload a few of them to makerworld. I already have four materials set on this model in Blender. Is there any way to export this as a 3MF file so that the slicer will see the materials, but I would prefer not to have to go ahead and try to select them all again, considering the hard work is already done?
