De-Activate or Do Not Active when you re-image a single host in a pool

Sometime I need to reimage a single host to test a configuration, but as soon as it comes online it is activate, an those sneaky user jump into the host before I can deactivate it.  As on the host pool when you add a host you have the "do not activate" it would be nice to have the option when you just reimage a single host.
