Changing the names of multiple blocks in a DWG

I've been given about 14 DWGs from another company all on different discs. Each DWG is a page to a set of Shop Drawings. All objects are in model space. I want to combine all of them into one drawing but every drawing has similar block names with different objects associated with the block and when I copy the objects from one drawing to antoher, the blocks morph into the exisiting block, if that makes sense. Just a poor initial set up.

Anyway, the solution to this, I have found, is to rename the blocks in each drawing to have room numbers on the ends, giving them unique names and avoiding the "morph" upon inserting. I have about 15 blocks per drawings to add -XX with XX being 01-14. Is there an easy way to modify them or do I need to do the RENAME command as many times as needed in each drawing? Is there another solution to this that I may be missing? If you don't understand this problem, I can explain further. Thanks.

How about xref'ing the drawings, and maybe Bind or Insert, whichever suites your needs better?

Interesting solution, nestly, but you would have to use the "Bind" option because that renames the blocks. The "Insert" option does not.

Thanks for the suggestions. I'll play around with both of these today, I'll let you know if this works.

Perfect. Exactly what I need!!! You guys are awesome.
