So, that's the skinny -- the rescuer would like to place these girls together, which would require a breed-savvy person.
Usually female placements together are not great, because of pit bulls' innate dog aggressoion; however, if the right adopter comes along, who is willing to crate one dog while they're unsupervised, etc., this would be a match made in heaven!
I would prefer adopting them out individually -- if outstanding apps come in for individual adoptions, those will be of priority --
For those interested in adopting them together (or separate!), please refer to my section on dog aggression here.
