XMT / RCV 0-99 is the extent of it. Often, you'll see the Channel Mode messages [CC120-127] excluded, and there's a good case to be made for leaving out CC99-101 [NRPN and RPN]. I think that Eventide [like RLD, Sequestial Circuits; and others] falls under that "100 out of 128 by design" camp.
I mentioned a hardware translator here. Some sort of MIDI pedal sending CC100 before your effects chain comes to mind. Most MIDI host / DAW applications can convert CCs easily. But I can't think of another way out of your dilemma without adding some external hardware to the process.
I have looked into the TimeLine in the past. There may be a way around this by making the Strymon the 'master', and 'slaving' the Eventide pedals, but I don't know its feature set well enough to be certain.
