required functionality

Hi,

I would like to know if the next functionality is included in the plugin.

There should be possibility of having items (goods) inside of every day.

These items should be dynamically changed when for ex. a user orders some items from a particular day, for a period of time (like several days)

Is it possible to achieve this with your pro version ? or to modify the code if needed.
Do you have a demo version with calendar to play around, to see if it suits my needs.

Thank you !
