How do I tell SABnzbd to use a backup server for missing articles on my main server?

I have 3 servers, the first one is my main server with Usenetbucket, the other 2 are slower but much better with old nzbds that may have articles missing on my main server.
I only want to use the 2 backup servers if there are missing articles with my Usenetbucket server.
In the past, there have been situations where I've had to do this manually, whereby a single part of a large download is missing hundreds of articles (unrepairable), so I have to restart the nzbd download (filtering only the parts with issues) with my main server disabled, and one of my backup servers enabled, and usually I'm able to finish my download this way.
It's a massive hassle though, if I could just mark a server so it's only used for bad articles on my main server, that would be ideal.

set you main server Usenetbucket to prio 0

set your backup servers to prio 10

OK, it's important however if the files are healthy on main server (around 99% of the time) then I don't want to touch these servers.
I have limited data allowances on these 2 backup servers so I only want to use them when absolutely necessary.
Assuming I set the priorities to 10, can you assure me that it will only open a connection with them when there are missing articles on the main server? My understanding is they will still be used for healthy downloads.

No, it will only be used for the missing articles. Your scenario is exactly what it is designed for!

Yes. That's the whole goal of priority.
