VraySwitchMtl controlled with more settings.

It would be great to have more control options available in the VraySwitchMtl. In complex scenes, I often use ObjectID to manage my maps. However, doing this with VraySwitchMtl is more challenging.

I have found a workaround by using the VrayMultiSubTex plugged into the VraySwitchMtl slot and setting it to Object ID mode. This method provides the controls I need, but I believe it would be more user-friendly if these settings were integrated directly into VraySwitchMtl.

Additionally, I would appreciate the ability to increase the number of material slots in VraySwitchMtl.

In short, having a version of VraySwitchMtl similar to VrayMultiSubTex would be a valuable improvement.
