Pharan, select bones or regions, copy, select other bones or regions (bone hierarchy must match), paste and the SRT is changed to the copied SRTs. This is obviously useful for bones and can make copying SRT between images in different skins easier. One somewhat tricky caveat is that you must choose local or world axis, you can't paste with parent axis chosen. I just added a toast message for that.
mfedorov, it works for me when using selection groups to select the bones. I'm guessing you had the parent axis selected, so the new warning message should help.
