Inspectors and tags

If I specify tags using Unity's object Inspector it seems that I cannot browse those tags from Behavior Designers Inspector when I'm editing a task for example Can hear object where it is possible to specify a Target tag. Instead I have to type the tag.

If that is the case I'd like to suggest if the Behavior Designers inspector could be improved so that defined tags could be browsed.
This would improve workflow because there would be no need to type again already created tags. This would also prevent typing errors.
