Is it possible to lock the Computational Domain in Flow?

(This is more of a rant than a question)

I'm stuck in 2011 so it might have been "improved" in newer versions of Flow...  I'm wondering if you can lock the computational domain yet? 

Everytime I make a change to a model it brings up the "model has changed, do you want to reset the computational domain".  The default is YES.  But I've set the domain as I want it for external simulations of this model assembly.  It's a real pain  when you're working on doing a lot of things and it changes the domain to something ridiculous to have to open a previous configuration to determine the dimensions to reset the domain.

I know you can get around this by turning off Automatic Rebuild, but I like everything about auto rebuild except the desire to "update" my computational domain.
