Conditional Formatting Based How Recent An Update Is

Currently the closest to this seems to be:-
Last Update | Is After | a Chosen Date.

It would be helpful to also have:-
Last Update | Is After | x Minutes Ago

Doable?

Hi,

It’s not supported under current structure, it needs to count every single minute, it might be a heavy loading to system.

How about instead an option highlighting each update for x minutes? i.e. any update is automatically highlighted, and starts a jscript timer for x mins then unhighlights.
