Copy Vertexes Positions To Another Aligned Object

I'm trying to copy the 1st arm Vertexes to be the in the same spots as the 2nd arm Vertex how could I do that? (I'm easily confused with Scripting for any program)

But What I am mostly attempting is using Skin Morph Modifier to morph my character's right arm to their left arm but using the same right morph but I could not because I had to collapse the skin modifier (Not Skin Morph Modifier) to the Morph Target to be able to move the Vertices in the positions that I wanted. I think that bakes the Skin Modifier into the right arm Morph Target and it can't be used for the left arm so I want make the left arm morph the same as the right arm morph.
