Feature request: Luban add function to break loaded vector files


I’m starting playing with the laser and I found a limitation of Luban

I’ve downloaded designs that require cut and engrave, but all lines are on same dxf file
I have to open the original file in an editor and break it into 2 files, then load the 2 files, try to align them, and set one to cut and the other to engrave

It would be nice to have an option to “break” loaded files.
Basically add a group/ungroup option.
