Delete option for relationships, other fields

If a relationship category becomes outdated, currently it can only be removed by ending that relationship category between all entries. This is a manual time intensive process. I suggest that there be a place where one can simply manage all relationships (not the entry-to-entry relationships but the relationship categories), so that with a simply delete button, all the entry-to-entry relationships for one relationship category are removed. Much more user friendly and simple.

Similarly, if there were a way to manage other fields, such as in our customized version the record-type or issue areas, to add and remove issue areas instead of emailing a support request for every change, this would make usage faster and give more customizability to customers.
