Refresh Flight Number Button

[LemonButt]

When creating routes, I'd like to have a button next to flight number somewhere where I can refresh the flight number in the same way that changing days of the week will check the database and refresh.  Right now, I build an aircraft's schedule using multiple tabs and once I have it set, click confirm on all pages, knowing that it will refresh and update the flight number with an error and I can click again.  I'd think this would slightly reduce load on the server and make things a little easier when you know your flight number is taken already.

Also I just noticed that the auto-update on day change is actually hurting me when I'm doing 6/1 day scheduling.  If I click my 6 day schedule to create a new route like this, change the flight number, then update the days of the week to get the right 1 day, it refreshes the flight number.  This goes back to AWS being "smart" and pairing new routes to existing route numbers if they meet the requirements.
