I suggest you make your feelings felt in the feature request forums as well as here. It has been said a theme editor, which was only introduced with X3, is on the cards but no timetable has been set.
The quantum discombobulator on the Falcon had a small quantum dilation moment but then popped back into this existence, before settling into the groove.

You can "build" your own instrument definition .ini files in Notepad, I did this for my JV1080 expansion cards. If you open one of the example .ini files you can see the format and either edit one or create from scratch, I suggest try editing one. Is it a PITA yes but the effort is worth it in the end.
@Samuel Telson you can import instrument definition files through the Cakewalk plugin Manager, which can be found under utilities. You may find it beneficial to read the section on this in the reference guide as it is a deep topic.
@Sperry Alan, have you tried making a custom list? Its how I organise both my synths and FX.
I would also suggest to make this a feature request in the feature request forum.
Just one question have you muted all the tracks that feed the master buss. I have bounced the tracks down to a new track which is feeding the master bus. Then when exporting forgotten to mute all the source tracks.
