Messages/Inbox Check times

Sometimes I just want to check my YouTube subscription or Instagram messages and I fall into the trap of droom scrolling when I just have an app limit on the app. And when I set a lock I can only set one time, so for example 20 minutes as that is enough to watch a YT video but too much to just check the inbox, so Iā€™d love to have the options to set 2 times to an app lock.
Like that one could at first look into the app by just having access yo the app for a short period of time (like 4 minutes) minutes and then, if they want to, access the app for a longer period (like 20 minutes).
