I've been assigned the tedious task of creating dynamic blocks for the company during slow hours. One of the many is all types of fastners. I've created dynamic blocks on each size of screw allowing the user to align and stretch to the appropriate length but my boss wants several blocks in one (Master Block) but each individual block ( Sub Block) has several versions of itself ( flat head, pan head, hex head, ect.). I tried puting all wood screws (# 2, # 3, # 4 ect.) in one dynamic block using visibilty however, I loose the origional dynamics (stretch, array, align) of the sub block after inserted into the master block.

Any ideas on how to do this or even if its possiable?
