Que: Can the Job invitation sent to the users be customized or additional options be added?
 
 
Unfortunately, Invitations send to the users for the job can’t be customized or a new option is added to it as we can only have an approver or viewer for the job invitations.

Basically, send invitation option creates a guest access to the job and sends an email invitation to a non-tFLOW user to be able to view and or approve the job for a limited amount of time.  Options include sending the proof along with the invitation, as well as typing in a message.  Multiple users can be invited at the same time.  Time limitation for the invitation expiration is defined in System Settings: Other

If you want the user to be able to perform more actions in the job then approving or viewing than either we would need to create that user in our system or assign to the job if already created.
