Using F2 to edit TAG names

I have used the multiple vault to great success and now I would like to use tags to segregate my 850 odd items in my 1Password. I have done this semi-successfully however when I have made a mistake and the tag needs to change its name to accommodate a more hierarchically designed outcome I can't just change the tag and have the effects go through all of the records that I have created. I end up having to go through ALL of the previously categorised items in order to get the right result. I am hoping you would consider this in the next update. Thanks
