Selecting a date to show on the agenda with time grids

[Christopher Dimech]

Dear Compeers,

I able to run the command

(org-agenda-list nil (org-read-date))

to select the date and get the week for the agenda.

But I would like the grid marks for the selected date to show up
together with the list of appointments in the time slots.

Would be very grateful if somebody can help me further with this.

Regards
Christopher
