Please move Sort ascending link on custom field set-up screen

Please add the ability to Sort ascending / descending near the Save button.  When we have long list of drop-down options on a custom field, like Country:
1.  We add options at the bottom of the list

2.  Have to scroll all the way back up to Sort.

Thankfully, you have a split screen so that we don't to scroll all the way back down to click Save, but moving the Sort option near save would save us time.  :)
