I want to label a duplicate edge I have with different labels in an adjacency graph.

So far I have this:


    AdjacencyGraph[({
       {1, 1},
       {1, 2}
      }), VertexLabels -> {1 -> "v", 2 -> "u"}, DirectedEdges -> True, 
     EdgeLabels -> {(1 -> 1) -> "δ", (1 -> 2) -> "γ", (2 -> 1) -> "β", (2 -> 2) -> "α"}]

Which gives me this:

Is there a way to label one as `α_1` and `α_2`?
