I've read this posting with great interest as I too used to have these problems. How did I deal with it?

Simple - I purchased Fred Mellink's KN SD Explorer Tool which allows you to mix and match from any amount of SD Cards in any order you wish, using 'drag & drop' (Windows style) and the bonus is you can then print out an Index of your latest compilations.

I save everything to SD card and work from there. The SD card is loaded and ready for use by the time I have turned over my music page.

I cannot stress too much how useful this tool is.
