Why can't I import an encrypted digital wallet file in Test mode? (Bump, well?)

[pf]

When I click the radio button to import an encrypted digital wallet, the "Test mode" checkbox gets disabled. Why?

And of course, if I proceed anyway, I cannot import it because it has the same wallet ID as the one that's already there (of which the backup was made in the first place).

I want to test my digital encrypted wallet backup without messing with my current wallet.

Sorry to bump this, but I just have to.

I mean, what the heck? This seems like such a basic thing. I'm surprised it's not there.

What are my best options? Just delete the wallet from Armory and import it from the backup again? I guess that would work but isn't that kind of strange just for testing a backup?
