Publishing meeting invite to new addition in the DL

Dear Team :

                  Currently when we schedule any meeting for the "Delivery Group" under outlook, it delivers the meeting invite. But when we include any members to the "Delivery Group", they are missing the meeting invites. 

                  Is there any options to send the meeting invites for the new addition, without any manual efforts ( like opening the meeting invite, adding the new member ) ? 

Thanks

Pradeesh
