I would like to keep track of all the versions an issue has been scheduled in. I created a custom field for versions. I then do a bulk update at the start of the version of this field so that even if the fix version changes, I still have the original version there. However, if that same issue gets again re-scheduled, I now loose the first version that was already there if I do a bulk update. I would have to manually select both versions for that issue.
What I would like is the ability to say "add this new value to the already existing values" in a bulk change. This can be very useful to add a new label for instance to issues also.
