I would like to rename a selection of images using {iptcdate}_{caption}. I am unable to do so, as the rename button is disabled and there is a message in the Rename dialog stating "Please sequence or us another renaming variable". This happens even if none of the captions are the same. Even if the captions _were_ the same, I'd expect the collision settings to handle name collisions. Doesn't seem that using a sequence number would be necessary. The rename works fine with a single image selected.
Should I be able to rename this way or am I missing something?
PM Version 5.0, build 16438 (e61be25) on Retina iMac running 10.10.3
Thanks
