Thanks guys - what I was trying to describe (badly) is the following.
On a limited / throttled connection, I have a manually added NZB downloading a TV series of 19Gb (which will take a while to download). During this time, a show gets added automatically via RSS feed but gets added into the download queue below the TV series. During this time as well, I import via nzbindex.com (double click & import) which gets added in at the bottom.
In reality, I'd like the RSS feed to get added above the TV series and the manual add / import as the very first download as it's the one I want first. My suggested approach would be having a series of configurable priorities such as 1-5 with default of 3 for RSS import & 2 for manual import. These could be changed so in my example, I'd set the TV series to 5 so it would download eventually, but not at the expense of RSS or manual import.
