Allow adding selected photos from one album to another album #1597
Description
Is your feature request related to a problem? Please describe.
When browsing photos inside an album in Memories, there is currently no way to select a subset of photos and add them directly to another existing album.
This makes album organization cumbersome: to reuse photos in another album, I must leave the current album view and manually reselect the same photos from the timeline or folder view.
Example: I want to select 20 photos from Album A and add them to Album B without leaving Album A.
Describe the solution you'd like
Add an option within the album view that allows:
- Multi-selection of photos inside an album with a contextual action such as “Add selected to album”
- A dialog to choose one or more destination albums
The selected photos should be added to the target album(s) without being removed from the original album.
Describe alternatives you've considered
The current workaround is to go back to the timeline or folder view and manually reselect the photos to add them to another album.
This breaks the album-based workflow and is inefficient for large collections.
Additional context
This feature would significantly improve photo organization workflows, especially for users managing large libraries with overlapping thematic albums.
It complements existing album features by enabling album-to-album reuse while preserving the original album structure.
