SSMS: Bit column defaults to Expression when Group By is desired

Question

(Tested in SSMS 2005 & 2014)

When I have a table or view open in Query and View Designer and I turn the Group By feature on, any bit columns defaults to Expression.

Is there any way to change this (by options/settings, registry tweak, or other) to default bit columns to Group By?

Thanks for any help anyone can provide,
