Screen Time - Continuous vs Overall Limit

I know I can create an overall (total) limit but is there a such thing as a continuous limit? For example, overall I want to let me kid use his device for 6 hours per day but I only want him to be on it for 2 hours continuously. After 2 hours, I want to force him to take a break... and then maybe 1 hour later the device unlocks and he can use it again for another 2 hours... etc. (up to his 6 hour total limit). This way he isn't just sitting on it for 6 hours solid in a single session.
