We regularly use the queue and file naming templates for doing dozens of renders at a time, e.g. for instruction guides. We'll often have dozens of Model Sets and/or Studios we need to send all at once, but overwrite old ones so that our users can let their links update from one place in Adobe InDesign, etc. when adding model sets or studios to the queue, you're asked if you want to over-write, it takes several seconds (sometimes up to 15 seconds) for the next dialog to ask.
A simple "Yes to All" or "Overwrite All" button would be AMAZING.
(Yes I realize I could move files out of the folder or render to a different placeholder folder and move the files where I need them)
