Annotate mullion

Hi guys,

I am using mullions to create 2x4 simulation. to get premade orders.
I successfully classified it by color according to length, but I was wondering, is there a way I could annotate it by section without duplicating each section 1 by 1 and write manually how many 2x4 there is in that section.

Thanks for your help!
