agenda template change

I have all of our meeting agendas available in the drop down box to 6-30-19. If I want to change a line item on the agenda for all the upcoming meetings, ie, just want to add the words "and Toastmasters Mission Statement" to the SAA duties in the description box. do I have to delete all the existing future agendas & replace them with the agenda that has this phrase added?

You have two options: Update the agenda template, delete the agendas and recreate them or edit each of the agendas.
