Love the software but hitting a few technical bumps

Hey Dave and team, love the software and have been using it non-stop since I discovered it! It's pretty incredible in both concept and execution, love how user-friendly it is--but I feel that I may be running into certain limitations because of that user-friendliness, to be honest, and the lack of Advanced boxes in certain contexts or fatter toolbar menus/preferences. For example:

1. I want to "group" triggers with a single hotkey--say I want both eyebrows to achieve a certain pose or mirror in certain instances, for that I'd need a single "parent" key that would activate numerous triggers but each of those having their own respective "child" keys for the flexibility of individual control when need be. Initially I solved this by duplicating artwork but that was a bit tedious, currently my solution is scripting through AutoHotKey for any amount of overlapping groups but I don't know if there's a native solution or one in planning.
2. Is there a technical limitation/ceiling to the number of triggers possible? Can it be extended beyond the keys I'm physically able to input? My current limit is 65 but I really need it to be higher than that and I can't always use Digital Puppet's Latch trick for certain components because they need to be simultaneously active or available, plus I'll be using *more* than just Ch at once so I need some of those single keys for other purposes--realistically I'm down to something like 50 max over here. Can I enter the virtual key value to assign a trigger rather than physically pressing it? If not that, modifiers like shift, ctrl or alt or combinations between would make a world of difference though I understand they conflict with program hotkeys -- I already know I can't use modifiers but I'd like to at least echo that request because I really really really need more than 65 without latching. I can use AutoHotKey again to bandage this through scripting but I can't yet get my artificial key input to register within the trigger's text box. Will/Should/Can artificial input register? That's all I'd actually need, but it'd be really nice to enter a virtual key or scan code for advanced precision, and ideal to have some Ch-specific modifier key or something like master latches to multiply the trigger possibilities exponentially.
3. Am I able to record more than one Camera Input on the face, in the instance that I want to record the general movement and the eyebrows individually? I feel like I've seen it done before, can't find it again, and keep being forced to record eyebrows along with head tilt in the same take otherwise they overwrite one-another, unless I'm arming things incorrectly?
