Can I save a member invite list to send later?

Yes you can - Lists belong to your facility, not to one person. If your shift ends before you finish, a colleague with access can open the same list and continue.

• Where to find your saved invite list: Users > Invite Members
  
  The saved list will be summarised on this page, with an option to Continue. 
  
  
  
  
• Re-checking: every list is validated again when it’s reopened, so the number you approve is accurate at that moment. Your count may change if members have joined or opted out since you last looked.
• Who can resume: [confirm which user roles - anyone with owner access?].
