Clay, I found you a cool trick. Just tested. It works.
Use the FLATTEN command. Select that block. It'll turn it into a copy of the block with "-flat-1" amended to the block name.
However! It will keep the new rotation, if you rotated the original while placing it.
Alternatively, you can save the changed copy back into the plan graphics folder as a new block name using our Save Block tool so you always have the new version.
