Can Snaplogic Throttle on behalf of a receiving applications basis a number configured

Hi Experts, We have a problem we are trying to solve using snaplogic. the flow is as simple as this but with multiple application
(Application 1 + Application 2 + Application3 ) -> (Feed Master) + Snaplogic -> Application 4
To ensure Snaplogic received everything we have put Feedmaster, now how do I ensure we can throttle the message based on Application 4 capability.

You may consider Application 4 has Rest API capability with certain limit on concurrent calls

Look forward for your inputs
