Is there an option in CiviMail to allow us to add individuals (not groups) in the Recipients field when creating a new Mailing? (we're using Mosaico/FlexMailer, if that helps).
We're trying to avoid having to put people into temporary groups each time we want to send a mass mailing. Sometimes new individuals come in after we've sent the mail mailing, and we want to resend only to those individuals, without having to add them into a temp group and then delete the group.
If there isn't an out-of-the-box option for this, any pointers to where we might be able to customize the new mailing screen to add this?
