The thing precisely is there is no box such like that. Contrary to drum programs, which provide a "type" submenu with two choices (program, pad), we unfortunately don't have access to a "type" submenu with two entries (program, keygroup) for a keygroup program. Worse than that, we can't automate parameters for all keygroups simultaneously.
To sum up, keygroup parameters (not the ones belonging to the program, but those which belong to a specific keygroup, or all at once) are not q-link assignable nor MIDI learnable. For the cutoff and resonance parameters, there is a workaround consisting in assigning a filter in a program insert (assuming that a slot is available), but for the envelope, we are powerless
For hip-hop producers, it may not be a problem, but for electronic producers, it could be frustrating. Imagine you sample your analog synth with the super "autosampler" feature. You set a length about 10 seconds for each sample, with a very tiny attack set on the envelope of the hardware synth. That way, you think that you can modulate the release on-the-fly to make a progressive legato to pizzicato effect on a running melodic sequence. You can't. Same thing if you try to make the attack more smoothly.
I assume that it may not be the Akai team's priority (multitimbral MIDI and audio streaming, to name just a few, are probably more expected), but this feature misses for some people. The MPC Live is called Live and there are some inconsistancies which don't allow us to be fully comfortable in live situations, this thing among others (mute assignements, q-link leds, select a pad without triggerring it in main mode, erase pad notes without the erase gate function, looper buttons not learnable, etc.).
