I don't think it's available at the moment. 

I made some attempts in the past to implement this, but if memory serves me well I ran into issues to properly use conditional arguments together with parallallization.

Maybe there's another part of the analysis pipeline that you could parallellize? Searchlights are parallellized, and if you want to compute a series of null maps for permutation testing, then those could in principle also be generated in parallel.
