Slicer Selection (multi select)

Hi Guys, how are you doing?

I have a simple question I would like your help solving. I have a slicer, and we allow many selections. I would like to know if it is possible to know which section has been selected first. (Need to be in the same slicer)

I want to do it because I have a calculation that needs to consider this order. For example, my calculation is Budget/Forecast. In this case, I would like to define (in the same slicer) which version I want for each of them.

I know that it is possible using the minimum and maximum, but my Type doesn't have an ordered name.

Thank you
