Fermentation and age profile question

I am new to BeerSmith. I will use it to brew a 10 Gal batch of beer later this week.
I ferment in two 6 gal carboys. How do I Create a second Fermentation and Age profile for the second carboy that is associated with the batch session?
Thanks,
Rick R

The program only allows for one fermentation profile per recipe.  I have split batches for different yeasts, dry hopping schedules, etc. many times.  Normally, I brew the base recipe and then make copies for the fermentation split and do any customization using one of the copies.
