End Of Day Reports - Royal Mail

Just a quick question in case anyone has come across this…

I’ve been making a head start on orders that need to ship tomorrow and for most of them I remembered to change the shipping date on buy shipping to tomorrow’s date. The ones I forgot to change are on todays manifest.

Do anyone know if the orders I changed the date on will appear on tomorrows manifest or do I need to do something different?

Thanks in advance
