UK Brass band Template

I think this is already done in the Nightly builds of 2.0

2.0 will indeed have "linked parts" which work more or less like the Sibelius and Finale equivalents. A single command automatically generates all parts for the score, they are saved as part of the main score file, and links are maintained so that an edit to the score automatically reflects in the part and vice versa. To be sure, this facility is still perhaps not all that well tested and could benefit from more people trying it out. I've reported the issues I've found.

However, even in 1.3 there are things you can do to simplify the process. First, the template itself can have the parts already defined. I see the UK Brass Band template does not, so have to manually set up the list of parts on every score. So if you're going to make your own customized version of this template to correct the issue with the cornets, you might as well also go ahead and go through the part definition process - defining the parts in File / Parts. Don't actually create the parts, just fill out the list in the dialog. If you save your customized template with this already done, the parts will already be defined in the scores you create from the template, so all you'll have to do is hit Create Part for each.

My usual workflow is to create my score, then make a copy where I change the formatting (size / orientation of paper, size of notation, etc) to be more appropriate for parts. I generate my parts from that copy. I generate all the parts at once then immediately go through and save each. Once you've set the correct folder for the first part, the rest automatically go to the same place. Also, due to a bug the indenting doesn't work properly, so before I save I click in the indent area and hit Delete to remove it (I believe it's actually just an instrument name full of spaces).

With good formatting settings, I find the parts come out looking pretty good out of the box, but usually require some manual adjustments here and there. Still, I like to run through and save everything first before spending time on any given part.

For 2.0, File / Parts will have a single "New All" button that automatically defines and generates all parts in one step, and as mentioned, the are automatically saved as part of the score itself, with all elements linked between score and parts. So that's a pretty big time saver. Also, there will be an option to control the formatting for parts, so one shouldn't have to first create a separate "parts score". Not sure if that facility works yet or not - I think it didn't last I checked. But all indications are that as of 2.0, the management of parts should be more in line with Finale and Sibelius.
