Hello!

I write schedules for work, and I want to know how to push a schedule to start later (or pull one up to start earlier) without having to manually change each block of time. IMPORTANT: Time blocks must be within the same cell under the following format: "10:30am-11:00am", the two times cannot be in separate cells.

Basically, I want to know what the solve is if I write a whole schedule to start at 10:30am and then decide I want it to start at 11:00am instead. How do I avoid having to manually retype all the blocks of time?

Thanks in advance!
