When inviting organizations to a Funding Opportunity, have the option to select a "Mailing List" group
We have several groups of Organizations saved as a "Mailing List", for easily pulling the list or to send a group email. It would be really helpful to have the option to select one of those mailing lists when inviting a group of organizations to a Funding Opportunity in the Program Manager.
The steps could be to select a radio button option: 1. Add Organization, or 2. Add Group. When selecting the Group option, the drop-down menu of mailing lists is available to select a group of organizations that then can be added to the Funding Opportunity all at once.

Could you clarify or provide more detail on what you're aiming to achieve? Is there a specific reason the email broadcast functionality wouldn't meet your needs?
