is there some way to uncontract indices in tensor functions? Uncontract with Pair->All seems to only work for scalar products of vectors. Here is an example:

Contract[TensorFunction[t, a, b] FV[p, b]];
Uncontract[%, p, Pair -> All]

gives t(a,p). I did not find a way to separate the tensor from the vector once they are contracted unless I explicitly perform a replacement on the full form, something like:


Is there some more straightforward and systematic way to do this?
