Appointments list for a single day

I have made a webpage for my client that she can print each morning to show her massage appointments.
http://www.massageoplocatie.nl/schema/

The first table ("Alle afspraken") is generated by Appointments+ through the short code: [app_all_appointments]

I would like this table to show the appointments for a single day. Would that be possible by adding an attribute to the short code? That way my client would only have to change the date in the short code in order to print the relevant appointments list.

I couldn't find this on the Shortcodes page in WP. I hope I missed something.

TIA
