I did a quick recipe and chose a single infusion sparge profile for the mash. When I went to the vols tab I saw that the "Tot Mash Water Adds" was roughly equivalent to "Sparge Vol". I went to the Mash Profile Editor and verified "Use equal batch sizes" was checked. I also noticed if I checked/unchecked this box the mash in volume didn't change. I also checked/unchecked "Drain mash tun before sparging" - no effect.
The help link within "Mash Profiles" links to the BeerSmith guide for Batch Sparging where it states it will create equal runnings using:
Two stage batch sparge additions:
batch_1_sparge_liters = (boil_size_l/2 ? mash_water_l + grain_wt_kg * 0.625)
batch_2_liters = boil_size_l / 2

I don't see a way using the built in mash profiles to get this result.
