[Tags] Allow Tags to be managed in Bulk (Add/Removed) to Saved Objects

[nicpenning]

Describe the feature:
Today, I have seen issues with duplicate tags due to accidental imports of saved objects that duplicate tags which cause confusion.

Even out of the box tags may accidentally show up as duplicates over many years of using the product.

For example:

I can find no way in the UI to select X amount of objects with tag 1 and then assign correct tag 2 and then remove tag 1 from those objects.

I know you can delete the tag from all objects that have it, but I want to be able to add tags before doing so.

Perhaps on this page, you could have a another button to manage tags or combine it in the Tags filter.

Describe a specific use case for the feature:
The use case here is selecting manage saved objects or even just dashboards that may have been created by our team and then be able to remove all tag X and add tag Y. This would be similar to Fleet agents (however, that is a feature that could use some TLC as well.)

The docs seem to show adding tags to multiple objects but I can't remove tags before hand. The key here is being able to have all assets with tag X that I can then apply tag Y to.

For the example above, I would find the most recent version of the "managed" tag or the correct one that should be in existence and then remove all the accidental ones that could have been created from cloning dashboards improperly.

Docs I used: https://www.elastic.co/guide/en/kibana/current/managing-tags.html

I really enjoy the tagging feature as it helps a lot with organization but this feature would take it to the next level.

Thanks!

This seems similar to #143746

A modernized version, but yeah, looks similar.

@ek-so @kevinsweet - This would be a bigger lift, needing some design and PM input. Volley to you! Should we do this and add to planning board?

To add to this — perhaps it's just my lack of context, but I also don’t quite understand why we don’t allow adding tags (or even bulk-adding tags) directly from the saved objects table. This could be an enhancement to consider as part of this task.

i'll add this to the list of potentials thanks. it's a good one, but need to incorporate into the broad set analysis. tldr: not planned yet but agree there's clear value in doing something here
