Can I add additional sessions to an existing training in the calendar even if sessions have already been created?

Only Catalogue Managers and Category Managers (only for the assigned categories) can add additional training sessions to the calendar. Go to the left sidebar > Click on "Talent Management" > Select "Training" > Click on "Catalogue" > Select the category > Select the training in the category > Click on the "+Add" button next to the "Training Calendar" field to add other sessions > Select the dates > Complete the other fields > Then click on "+Add".
