Delete unused or old segment in SC15

[#1]

Hi, Is there a way to delete unused or old segment in SC15? If not, it would be nice to have it.

You can delete segments but you have to use the data warehouse interface.

It should be in the SiteCatalyst UI though. It's pretty annoying to have to go over to Data Warehouse just to delete it.
