We use Power Automate to forward critical email alerts to our on-call employees. Every week, we have to update the email recipient address in several flows due to a new on-call person. I am suggesting that a variable be created (e.g. $OnCallNumber) that can represent an email address. That way, we only have to change a variable value in one place instead of email addresses in several places. This variable idea could be used in other areas as well.
