For a device that is supposed to be infinitely customizable, it has a limit that can be reached fairly quickly. I'm topped out on mouse memory usage, what is this memory limit? Upgradeable? 

Been deeply customizing all of the apps I use and absolutely loving this beast, but for the first time I feel limited after reaching this memory limit. How can this mouse be advertised as the most customizable mouse if it runs out of memory with 18 or so profiles?

Coming from the G502x lightspeed plus where you have an unlimited amount of profiles, I'm confused about how this memory works and why you couldn't use the mouse in PC link mode. I'm not interested in keeping the profiles stored on the mouse. Why can't the Z2 just communicate with the X1 app itself for instruction.
