Document properties: Units in sheet format

for my drawing, document properties units is set to fractional.

is there a way to get a specific annotation on a 2nd sheet to ignore doc prop and read as 3plc decimal?

A vendor of mine has requested that I add material thickness to my DXF to make quoting simple for them. I can add the annotation to a sheet format then push to all my drawings with #task but I cant find a way to get it to read as .375 instead of 3/8"

I cant change the doc properties as it would mess up all my dims that need to be fractional.

Any thoughts?
