In the AWC-708c Laser Cad program it has a feature called clip box. this will allow you to cut at a very low power, a square out of the paper mask so that you engrave in that area only. Of course you will still have to peel the paper out of that area before engraving. I was just thinking this would be a great feature to add to the LightBurn software.
Just create a square on a seperate layer and set the cut settings to low power. No need for a “Special Feature”
