how to link cell attachments to another cell



is there a way to link cell attachments to another cell? I am essentially trying to create a BOM below an assembly drawing with each of the part drawings, however the part drawings are already saved elsewhere on Smartsheet, so if I create a new cell with these drawing without linking, it is likely that one of the cells will not be updated if I upload a new version of a drawing. I have tired linking cells normally but this does not seem to include the attachments which I find strange.

I would be happy to create an indent underneath the assembly if need be and create new rows below each assembly and link this way if need be.
