sadly no.
It has never been written although it is "just" an engineering
problem and not a "science" problem at least for the multi condition case :)

indeed you could use a morphed source space but you would still
have to pass each forward solutions unless you find a way to avoid it
by some clever preprocessing. I don't know how.

yes that sounds really reasonable. Let us know if you need
help to look into this.

no pb
