A d-dimensional lattice polytope P has index r if rP contains an interior lattice point m and rP-m is reflexive. I am trying to figure out if polymake has the ability to compute the index of a Gorenstein polytope but I haven't found anything in the documentation. Does polymake have this capability?

Yes polymake can compute whether a polytope is gorenstein and the index. See here. polymake can also compute the GORENSTEIN_VECTOR m.

Don't know how I missed this. Thanks!
