that could work and might be the easiest for you, or you could create a special command and trigger it with the VC.Loaded event which is fired as soon as VC loads up for the first time.
for help with events you can watch this:
really, you can put it into any command you want as long as it gets executed once before your TTS. You could put it directly into all your TTS commands if you want but that's a bit of a waste.
Please watch the video and see if you can figure it out. If not, I'll create a command for you that you can import. I don't mind doing it, but I also like to see people learn about the features I worked so hard to create!
Let me know how it goes.
