removing auto generated tags from collection and keeping them gone

[mwalker]

Collections when merging are creating tags for every item in the collection and it’s taking over my entire history screen. Is there any way to remove them without deleting each tag one at a time, or just turn off tags all together? Also I’ll go in and manually delete the tags and refresh the history to make sure they’re gone but as soon as I start to run a work flow all the tags come back.
