Reading plan dates off and feature to change today’s sections

Hello,

I have already been reading my physical one year Bible so I set my start date back in the app for the one year plan, but the app still sets day 1 as today and then if I click through like I completed the days it won’t shift my dates forward. A feature to shift the dates forward so you can read ahead on plans or if you miss a few days you can shift the dates back would be great. Thank you.
