How to quickly understand the layout in various digital console

Well i don’t know if am asking this question on the right platform but anyways i can’t help it so I’ll still put it through. With the rapid growth in digital processing from various manufacturers especially in the area of digital console were two different audio mixer does not have the same layout, routing, gestures etc. This really tend to makes things a bit cumbersome for me because alot of the time am i might be called upon to render a quick service to a club house or church with a console am not familiar with, so i have to go through a quick snippets to find myself around it which is not cool for me. Therefore my concern is, are other engineers experiencing this challenges? Is there a better options to find your way around this different interfaces in digital console now, or in the future? If so what are they so i can keep up to speed?
