When using Automation's to add a tag to a contact it does not simply add a tag. It first deletes all of the tags and then adds the one from the automation Step. Could this be changed to just add the tag to the existing ones.

I know that we can use custom fields to filter data in place of using tags but it would be really nice on a contact to also see all of the tags that we want them have AND be able to use automatons to do this.

The automation would be to append the tags and not replace them.
