Yes. You can add the journey to you pass when you are on the platform waiting for the train.
Especially if you have a flexi pass the advice is not add the journey to your pass in advance, but just before you board the train. If you add the journey to the pass in advance and thus activate a travel day and your plans change, then a travel day might be lost. It is only possible to remove a travel day until 23.59 CET the day before.
