As an Admin, I would like to be able to edit custom field options that have already been created and tagged on assets. Currently, making a simple change like going from singular to plural (Bread to Breads) requires the creation of a new option and retagging of all assets before the old option version can be deleted. If keyword tags can be edited, why can't custom field options? (Other DAMs allow for these simple edits to established taxonomy without all the extra work.)
