P: Creating PS Panoramas needs a new workflow

Hi. I tried Photoshop in addition to my Lightroom CC as the only option how to merge photos from Lightroom CC. And it was a pain, I reduced my Adobe subscription back to Lightroom CC only in a day.
Here is the thing:

1) I have like 21 panorama photos in Lightroom CC
2) I select those 21 photos, right click and... oh, 'Edit in Photoshop' is greyed out
3) I spend several minutes by opening those photos in Photoshop one by one
4) In Photoshop, I go to Automation, Photomerge
5) There I am said those photos must be saved first in order to use Photomerge (WTF they must be saved? They are saved since I have Lightroom set to store originals locally)
6) Searching how to save all 21 photos at once
7) Saving all opened photos one by one
😎 Photomerging, finally
9) Wondering how to send great result back to Lightroom
10) Saving to desktop folder, then manually importing into Lightroom CC
11) Finding I have now 42 panorama photos, everything is duplicated
12) Manually deleting every second panorama picture
13) One panorama finished, moving to another.


THIS IS EXTREME PAIN! DO SOMETHING!
