WIth your current situation, I think you'll have to override the Phase of the Link, under V/G.
I am not quite clear on the need for the Demo phase - attached are three images of a random project with an arch link. This was done with the basic two phases in each project (arch and mep). If you are looking for something other than what's depicted in these images, can you elaborate on what your aiming to show?
"I have a demo phase so we can keep track of it. our engineers change thier mind a lot, so I need to "Keep" the demo'd objects just in case."
Sorry, I don't quite follow you on this. Is this so you can easily find a demo'd elements and set it back to existing to remain?
