Looking for a way to change the My Vote to read as something else. We have a very sesitive user base ( I suppose that is the best way to say it) and we use Approval Boards with single inidividuals to create a custom approval process based on a selection from the person entering the ticket.
So it's not really a vote per say, but just "My Approval"
There currently is not a supported way to do this. You also cannot add/remove or hide buttons.
