I cannot save the invitee list in a template

I am trying to save a template for ad hoc meetings of a project team, but I cannot save the list of invitees as part of the template.  I go through the process of defining the meeting - including the invitees - and SAVE.  Then I save as a template.  When I call the template up in a new scheduling attempt, there are no invitees included.  That seems to be a gross oversight - so I assume there is some trick to it.  Can anyone help me?  I have been using the Zoom portal. Thanks.
