If I add my temporary object to the MOC, it automatically gets fetched and displayed in that window the very moment it is inserted; that's what I wanted to avoid because it is confusing and thus undesirable.
Use a separate MOC for your transient NSMO's. When you're finished, kill the MOC, without ever saving the changed (temporary, undesired) NSMO's to the PSC. Your scenario is a classic use case for multiple MOC's.
NSMO's are designed to live in MOC's. Seems like a very bad idea to try to get CD to do otherwise.
