Display Order of Objects' Edges

It looks like display order of edges are decided by display color of objects. Purple has always priority over yellow.
I’m an architect. I want structure (yellow) to have priority in display over finish (purple) Is is possible to change the priority?
Thanks.

Display Mode : Wireframe
Background color : Black

Hello- what happens if you Cut/Paste the yellow object?

Hi. Pascal.
Thanks for your reply
Do you mean ‘Copy & Paste’? If then, nothing happens.
I attach the Rhino File.

Nothing happens with neither Copy & Paste nor Cut & Paste.

Yeah, I meant cut/paste, in case object order in the data base might come into play - it seems not.
But, what do you expect to happen? The edges are coincident in space, what should Rhino do? (no, there is no draw order tool for edges that I know of.=)

i think there is no good solution. Maybe edges should ne dashed with alternating yellow/purple? or then object priority (draw order)
