Is there a way to configure an alert to be sent to multiple recipients using emails listed in a text file?

I'm digesting some Windows event logs and have an alert set up with the criteria that I want to look for. The alert works beautifully, but I'm adding another layer of difficulty with how the alert goes to recipients. Our admin team is constantly changing, so we maintain flat text files with email addresses of who should receive the alerts. Is there a way I can set the alert to go to the emails listed in the .txt file and have that update automatically if the .txt file changes? Use Case: I have an alert to go to our Schema Admins if the schema changes. When the alert fires, I'd like the alert to query the schemaadmins.txt to get the emails and email those users.
