Camera Raw/Lightroom: Merge to panorama - ability to combine the keywords from the photos into the pano file

Current behavior is for the Active (most-selected) photo of those photos selected for the Merge to Panorama to drive the Keywords for the resulting panorama. At this time there isn't a facility for merging the keywords during the panorama stitching process. 

I am going to convert this to an Idea (feature request) so that others who might wish for it can add their "me toos"

While you're at it, you could allow for adding default keywords or color labels. I tag all my panos "Panorama" (in case the filename does not contain "_pano.dng" for some obscure reason) and assign the yellow color label. Clicking on every panorama and keywording it "Panorama" is cumbersome, if you could assing this keyword during creation

Here's a simple way to assign the merged keywords to the panorama (it looks more complicated than it actually is):

1. Select the photos to be merged.  

2. Before doing the Photo Merge > Panorama command, go to the Keywording panel on the right of Library.

3. Select all the keywords and type Cmd + C (Mac) or Ctrl + C (Windows) to copy them.  

4. Now do the merge.

5. When the merge completes, go to the Keywording panel and do Cmd + V / Ctrl + V to paste the copied keywords.

6. Some of the keywords may have an asterisk (*) after them, indicating they appeared on only some of the photos.  Delete the asterisks.

This isn't as convenient as having an option to do the merge automatically, of course.
