Shortcut that enables cookies?

My Brave shield is set to “Cookies blocked” as the default setting. I then grant exceptions to all the sites that need cookies and that I care enough about. (I change the Shield setting to “Cross-site cookies blocked” for these sites.)

Is there a shortcut to change the cookie blocking settings without using the mouse? If not, how would I create an own shortcut for this, ideally without having to build/compile the full browser?

Thank you.

PS: MacOS most important, but I also care about the Windows and Linux versions.
