Access MorphTargetDelta of vertice in shader?

Is there a node to access the MorphTargetDelta of a vertex in a material? In particular, I need the morph delta for the currently processed vertex.

C++ equivalent:

skel_mesh->FindMorphTarget(TEXT("muhname"))->MorphLODModels[0].Vertice; // find your vert in there

I do not need the full vector though.

Thank you
