Trigger a process with variable interval inject (flow)

I need to trigger a process where I would like to change the interval of the trigger. Not like with a simple inject node that has a "hardcoded" interval value, but something that can be dynamically adjusted in the flow, or on the dashboard, or even from an MQTT message.
