Sometimes, when selecting multiple rigs for adding a comment in batch, you find some of them already have a comment. RE's current behaviour is to overwrite the original comments if you write a new one onto a multiple selection.
It would be useful if there were the option to append a comment, so that the original text is not overwritten and the new one is simply added after it.
This would come in handy for example when you want to add a comment such as "Till's Chimera Pack" to a number of rigs, and many of them have something in the Comment field already.
Since the tagging way is destined - or so it seems - to prevail over the "folder" approach, this option is indispensable IMO, unless we are given the possibility to add more custom fields to the records.
