Lofting circles on points

Trying to loft all the legs of this model at the same time, between 2 circles at top and bottom of legs. When I try to loft it doesn't go from circle to circle w same index like it does w the line, but lofts them all together. If I do 2 sublists and extract top and bottom circle for each leg and loft that, it works. Can I do them all at the same time or do I have to do each leg separately?

Thanks
