[Closed] Vertex-level named selection sets

Hi,
i’m trying to get the names of the vertex-level named selection sets created with a modifier (mesh_select or poly_select or edit_poly or edit_mesh) with the selsetnames option for the vertexSelection values.
If i write “$.verts.selsetnames” i get the names of the vertex-level named selection sets created at the base object but what i want to get are the names of the selection sets created at the modifier level.
Any idea?

Thanks in advance.
