bentching - (How) Should the wife of the ba'al habayit (homeowner) be mentioned in the call to recite grace after meals

As part of leading birkat hamazon (grace after meals) there is a custom for the leader to mention he has been given permission to lead by the male homeowner.

I am wondering if there is any discussion about whether or not to include, and if so how, the spouse (female co-owner) in this dialogue.

Ie: b'rshut baal habayit u'baalat habayit
