Isolated T-Shirt Design preset in Firefly?

In Firefly your gallery of reference images is helpful but I am trying to make images for printing on t-shirts and it would be really helpful if there was a preset that would keep the entire image in frame with no parts cut off the edge. I realize I can try the generative fill to fix this but it is time consuming and only works about half the time. Make "Isolated design" and option somewhere and make my life way easier.
