Bulk Delete Contact Tags
Please make Bulk delete contact tag in command settings. If someone accidentally chooses to allow a cateogry to upload as a new custom tag when uploading a spreadsheet they may end up with hundreds of custom tags in their drop down lists. Then to delete the custom made tag they have to delete each one individually in command settings instead of a bulk delete option.

If you reach out to your RTT, I think you should be able to correct this by reimporting the file with the correct tags.

Create one button to do delete in bulk tags.
I imported over 500 contacts, and it was imported wrong. Each contact has the wrong tag. Instead of labels they got imported as tags. Now I have a as many tags as II do contacts! All bad tags that takes more then 3 clicks to delete each tag.
Now what do I do? Go through my tags individually to "FIX" my import ERROR?
