I and many other players love the way you think, and welcome the opportunity to transmute regents in bulk format.
I know its a matter of time before something like this becomes possible; because the fisherman in the Commons allows you to click on multiple fish to sell them one at a time; or all at once.
I believe its only a matter of time before KI programmers can figure out how to do this throughout the entire game, to automate or streamline multiple functions; including transmute regents.
