Automate instrument effect macros?

So in the instrument editor we now have these super cool macros for controlling multiple instrument effects parameters. Way cool! My question is, and I hope this isn’t a dumb one, how do you automate the control of these macro knobs within a song?

With normal track effects I would typically either right click a parameter to create an envelope, and then Renoise would tell me the code for that specific setting that I could then put into the pattern editor. It seems like both the instrument effects, and the macro knobs that can control them, don’t work the same way. If there is no way to automate them, are they just simply for fine tuning and then leaving at one setting throughout the song?

To automate instrument macros in your song, use the new Instrument Macros meta device:
