Society SABRE

These Sabre PNRs don't have nearly the amount of information I'm used to having access to in Apollo. I guess I need to add tour lines to make some notes for my reference. I can't find how to enter a tour line, like Apollo's

Does anyone have this information?

I'm so certain I'm going to drop balls!!
