Could you tell me if it is possible to copy the structure of a schedule without the data?.
Yes. If you have a schedule which you have formatted and would like to create other schedules with the same formatting, follow these simple instructions:
Open the schedule with the formatting you want to use.
On the File tab, choose Save File and then Personal Template. (Name and save the template).
To create a new schedule with the template you just saved:
Choose on the File tab.
On the File tab, choose Open and then Personal Template.
Locate and open the template you saved previously.
