Solidworks Simulation remote mass reset

I am working on a simulation, and I assigned a body as a remote mass.  I then un-assigned it as a remote mass, but now it won't let me make it a remote mass again.  It says it can't be made a remote mass again because a body it was attached to was already a remote mass.  I am paraphrasing of course.  Any idea how to get SW simulation to forget that the object in question was a remote mass, short of creating a new simulation?
