Well how about this:

1. (one time only) make sure Options/Clipping/After Clipping/Assign Currently Active Tags is active
2. focus the source note and press Ctrl+BkSp to select its tags on the sidebar

3. go on with clipping => all clipped notes will be tagged similarly to the source note

Good news - the feature is implemented in V3.10 Beta 1! If you votes for this, check out the beta here:

Sorry that it's taking so long. You see, alarms is not core functionality for a note-taking application. We recognize that there a lot of demand for this feature, but currently we consider the task to rethink and refresh the UI to be more important.
