Automation for track FX bypass

If a track has CPU heavy FX but is silent for most of a song, it makes sense to bypass those FX while the track is not contributing to the mix, especially when the cumulative CPU usage of a project is getting near the system breaking point.

Although it is possible to set up master/slave parameter modulation to bypass multiple FX from a single bypass switch (which can then be automated), this is fiddly to set up and awkward to maintain (if you add new FX you have to remember slave them too).

An automation envelope to toggle the track FX bypass button would be much better, providing an easy way to enable/disable track FX en-masse during a mix as well as an obvious visual cue as to the state of the track FX at any given time. This would be extremely useful for users (like me :() struggling with underpowered computers.

Please?
