Dude, create a global token that gets inherited by each Program in a specific folder. That's what I do. Here's an example:
For our roadshow tour, we have program owners that we want to copy on any registration alerts. This doesn't change from city to city, but it does occasionally change when we have new hires, etc. Instead of changing across all the 20+ Programs, I just change at the folder level for those roadshow programs. It looks like this:
Text token: {{my.Internal Alert Distro}}
Value = email1@company.com,email2@company.com,email3@company.com
Then, I just paste that token into the "To Other Emails" field on the alert flow action and I'm good. All updates are made to the token and get inherited by all Programs in that folder.
