Where's that decent preset again?

Rapture Pro has two methods:  1) mark it as a favorite from the browser 2) create a new "instrument type" and this will allow you to search on that basis.  You don't need to use standard settings for this.  Create a category that will help you find what you're looking for, e.g. FAV_Arps. 
 
Sonar can do the same sort of thing if you are sorting plugins with the new browser features.  You can categorize plugs into arbitrary categories, but I don't know about specific presets.  Track templates?
