Is it possible to make a block "unique"? Much like you can done in Sketchup by right-clicking on a component and "make unique", allowing the user to make changes to only that component? When placing plan graphic blocks it would be nice to be able to make a block unique so that it can be modified without changing all other instances in the DWG.
I know this has been a feature in Autodesk Architecture. Or is there another process that I should be following?
