Edit custom sequence settings

There needs to be an option to edit custom sequences. When making a new sequence, you can save as a preset or delete one that exists, but you should be able to click on one under the "Custom" folder and make changes to it. I realized after a while that you can click on your custom sequence and then hit "save preset" and it will ask you if you want to overwrite it, but there needs to be a more obvious way. Also, to do this you have to rewrite the description. Once I labeled it the first time, leaving myself notes on the number of audio and video tracks, I had to copy that description and paste it into the 'save preset' dialog box again to alter it and then overwrite it. You cannot just edit the description or name without redoing it.
