Summary: Revit MEP systems for ducts, pipes, and electrical need the ability to maintain info when demolished and/or used in design options

Description: This is a long time issue which has needed to be addressed to make Revit MEP not a series of work arounds.

Add the ability to demo part or all of any system and maintain the information about the demo'd system as well as create the new complete system including some of the previous existing equipment. Allow existing, new and demo'd systems to work together the way you might expect.

Allow design options to be usable with existing systems which are partially demo'd and then revised with some new components to create complete systems for both demo and new, such that each design option can have a demo'd and new complete system which is schedule-able just like any other object can be scheduled and analyzed in Revit.

Allow the same system to be demo'd partially or totally in more than one phase, such that it can be added to or subtracted from multiple times...just like other items can be in Revit.

Maybe split systems with a split system tool so that downstream/upstream system items can behave together from this point before or after.

Allow a partial system which reamains after demo to connect to the new option or options.
