Is there a way to set it so that different buttons show in Lightning and in Classic? I've created a number of buttons that use URL hacking to prefill many fields - I can recreate them with Lightning Actions (for a much better user experience), but then my Classic users will be stuck without those buttons, or else I'll need to display duplicate buttons in Lightning.

In the interest of making the transition smooth for my users, I want to allow them to switch back and forth as often as they want, while learning the new system. Therefore, setting different profiles for Lightning users and Classic users doesn't work.

Any advice on how to maintain 2 different sets of buttons, one for Lightning and one for Classic?

Thanks!
