What is the best way to edit a small portion of a 12-up file?

I am making Christmas ornaments, and layer them out 12up. Is there a way to have Lightburn reference a single master graphic in an imposition? Sort of like the symbols in Illustrator, and a linked graphic in InDesign.

For reference, the part that I edited is in black.
I’d rather not have to reimpose this file every time I need to make a change to part of the design.
