Get backwards during live performance

Hello! I'm just starting to work with Reaper, and globally I'm very happy with it! One question though: I plan to use Reaper as a time basis for my band's live performances. And, in order to handle unexpected human errors during performance, I would like to have a fast shortcut to get backwards of (i.e.) 4 measures. I've seen there is an action for going 1 measure backwards, but it brings the cursor at the beginning of the measure, so if we were in the middle of a measure we get lost. I hope I'm clear enough as I'm not a native English speaker ;) Thanks!

Either create a custom action (4 times "back 1 measure") or just have the snap settings set to "whole bars" and simply click?

smart markers or action markers. not sure what they are called these days, but they are sws markers that trigger any actions.

Thanks guys! Amazingly fast answers! I've created the following custom action: - View: Move edit cursor to play cursor - Go to start of current measure - Go back one measure - Go back one measure - Go back one measure + activate Smooth seeking. It does the trick! Thanks again!
