I often render tracks individually so I can eq and compress as needed. With drums, for ex., I render kick and snare separately, followed by hats, toms, and cymbals on separate tracks emulating the process how an actual recording is made. All other instruments are similarly rendered to separate tracks to help with the mixing process.
Tedious, I know, but it does give you more flexibility during mixing, plus I use better reverbs and chorus fx that are not part of the TTS fx chain.
Not only with TTS, but all other softsynths and outboard modules get the same treatment, aside from real audio tracks. To those who remember the mix I did of Toto's I Won't Hold You Back, which was all virtual save for the lead guitar solo, you'll know what I mean.
