adding acceptance radius to Simple Move To Location

Unfortunately AI Move To doesn’t work with a player controlled pawn and Simple Move To Location doesn’t have the acceptance radius. I’m not good at vector math and google has turned up nothing. I’m trying to take the point of click (vector) the location of the player(vector) and move the player to the location of click minus a float radius (like the AI Move To does). Can anyone please explain how to get a vector of the clicked location minus a distance ?
