Dynamic Action to replace block inside the block? Can it be done?

[ntrapaniP2MMV]

Hey all, I'm new to AUTOCAD and loving Dynamic Blocks. Crazy question, Can you use the lookup table or another action to somehow replace a block inside the main block. For example, replacing parts of a outlet box to Edison, Twist-Lock, Stage Pin, 220v, Etc. This way I don't have to insert and updated five different outlet box symbols, but just one a drop down menu. Ideally, I don't want to insert and overtime update a ton different blocks with slightly different hardware.

Is there a way I can have my cake and eat it to?

With a VISIBILITY PARAMETER SET, you can create several VISIBILITY STATES for each nested block or element.

Please see if the attached example is what you're looking for.

There's a blue grip/dropdown on the faceplate's upper right corner.
