A better way to schedule multiple flows

I am looking for a way to better manage scheduling posts, I have many flows that end up posting to my website for different things but sometimes they overlap and kill the database on the receiving server due to overload of requests.

I am now trying to stagger the flows cron time but it’s very hard to manage the overall flows in a nice efficient easy-to-use way.

At the moment I am just having to resort to using the tag in the flow title as a reminder to avoid overlapping flows.

Be great if there was a schedule management system.
