Possible to reorder query executers?

[brossow]

For our implementation using iReport Designer 5.6.1, we have a handful of custom query executers defined and do not use any of the built-in executers.  When I add a new query, then, I have to scroll to the bottom of the list to select one of the custom executers.  While I don't want to completely remove the standard executers (you never know when you might need one), I would like to move them to the bottom of the list so the ones I use most are at the top.  Is this possible?  I cannot find a way to move them from within the iReport Designer options, and a cursory search of the directory where iReport Designer is installed didn't reveal anything that seemed a likely candidate for manual editing.

I did find the ireport.properties file in <user>.ireport5.6.0configPreferencescomjaspersoft and was able to renumber some of the executers, but that doesn't move them up above the built-in executers, which is where I'd really like them. Any suggestions are much appreciated.
