Hit File>Make a Copy and you can start editing your own itinerary.
Here you can see the date, day of the week, the city, train or airfare, the accommodations and how much they cost, along with estimated food and activity costs. "Other" leaves room for museum entrance fees (bring your student ID!), cab or uber fare, paragliding in Switzerland... that sort of thing.
I probably didn't spend $40 a day every day on food. But it all evened out in the end. It's better to have planned for a little extra than to starve!
Note the color guide. I used this itinerary months in advance for planning purposes. After each place or plane ticket was booked, I'd change the color from blue to green to know what I still had left to pay for.
