yes, this would be a helpful addition!
btw. i have two problems with the current plugin (v2.5.0 had it too)
1. i can select a hdri/exr only one time. After that i have to restart sketchup to be able to select a different hdri/exr. i can deselect it but not select a new one after that.
2. I get black faces without material on some faces in nested components using automxm, even with no material applied (default materal)
i have copied the bad objects to another sketchup file to isolate it but the problem disappeared in the new file, i don't know why - I'll see if i can reproduce it on a smaller file...
