How do you handle the Planner when traveling?

I travel for work a few times a year and usually end up with a stretch where I can’t ride at all. I’ve been marking those days as unavailable in the Planner, but I’m curious how others handle it. Do you try to bank some extra training beforehand, or just let the system recalculate once you’re back? Any tips for keeping things on track through travel weeks would be appreciated.
