Need to send a Quarterly request and a weekly reminder until all request are complete.

Need to send a Quarterly request and a weekly reminder until all requests are complete.

I can make the power automate to send out the email Quarterly Request ever 3 months. And I have figured out how to make the reminder sent out ever 7-days but I need the remind to start 5 days after the Quarterly request goes out and stop when all are complete and start again 5 days after the next quarterly request goes out.  Any ideas?
