Discontinuous render to single wav + cue?

I have this long long live take, and I want to put a sequence of discontinuous portions of this into several CDs. The material for each CD is not in order, some songs will appear on more than one CD, one CD will contain two songs from the first hour, and the he very last song of the day, and all in all about 2/3 of the take will end up on but must be kept in the project. What would be the easiest way to produce several independent sequences of noncontiguous parts and render each to a separate CD?

This is my personal workflow for self-produced CDs. If you're producing a CD, I'm going to presume you're mastering it yourself. If it's just to listen to your tracks on different systems, the car, the Albert Hall, etc, then you don't have to think so much about this. I line the segments (CD tracks, or items to make up CD track) up on one or two REAPER tracks in the order I intend to burn at, and place a track marker in front of each segment, with one at the end of the CD play zone. I check the levels and any limiting, adjust compression, EQ, MB comp, etc to make the tracks sit well together -I will check LU here for reference. I adjust the inter-track gaps and the "track" markers, flicking backwards and forwards with "[" and "]" during playback until I'm happy with spacing. I name the "CD track" markers and put a "#" in front of the titles. I set the time-selection to the first and last markers (the last project marker is not #-prefixed, not a "CD track" marker). I then render to "CUE/BIN" (CD image) based on time selection bounds, with tracks denoted by project markers prefixed by "#". I have an old EEL script that easily toggles the #-prefixes, sets the time-selection to chosen markers, aligns the markers to 1/75th second (CD frame) boundaries so they won't be futher nudged by the CD burning app, and displays the time-listing for tracks to check track and total times, etc. It's a bit clunky, but it covers some of the more fiddly bits to speed the layout setting somewhat. Hope this helps... >

Lining up segments: you mean you copy the bits that will be the Songs of a demo cd, and paste them in order into a new track, put markers in that track and then render that track? Is there a menu choice to just render one track? That would be very useful for producing a cleaned-but-not-mastered partial/demo copy for a customer.
