[Ifeffit] TiFe EXELFS Two Phase Co-Refinement Question

I am using Artemis to fit EXELFS data on a TiFe alloy. There are multiple interfaces between two phases (Im-3m, and P63/mmc) present in the data. I am attempting to co-refine using both phases to create a path list and using paths from both phases in the fit. My understanding of this process is that the software uses a linear combination of each path. However, that would imply that there is a weighting factor applied to each phase that would be correlated to the phase weight for that region.

I was wondering if there is a way to determine what the weighting factors during a co-refinement to multiple phases are in Artemis, assuming my initial understanding of the co-refinement process is correct?

Thanks for your time,
