Working on plans for an office remodel.  Have a block for a door on the Existing Plan with continuous linework and want to have a similar block on the Demo Plan but have the lines dashed to indicate the door gets removed.  I have created a block for both but can't find an easy way to redefine the block for the doors to be demo'd.  Is there an easier way than deleting and re-inserting the new block - there's a lot of them!  Thanks.
