Hi Chelsea,
I've actually implemented your feature in OmniPlan 2.1, which we quietly slipped into the "sneaky peek" phase yesterday.
There are some rough edges yet in 2.1, so you may not wish to switch over to it for your primary work. Mostly we want people to have a look at our completely rewritten Microsoft Project support.
The sneaky peek and its release notes are available here:
