Ability to name invitations

Each invitation can be customized with groups, emails and others settings - but there is no way to describe or name them so that it's easy to distinguish between them without looking at the groups and other settings. This is a request to allow every invitation created to be named. In that way I can create invitation for example, that are aligned with marketing caimpaings with associated custom emails and group memberships.

ALSO, in this way, if you expose those names in the API that lists the invitations, then they won't look like the following in Pabbly when you go to connect a trigger in Pabbly to sending an invitation in Hearbeat.
