Dashboard Ticket Stat with Dynamic Field

[vulk]

Hi,

I'm using OTRS 3.1, I have 8 technicians for support my customers, I receive the tickets by email and I schedule visits in a datetime dymanic field, the schedule could be change then the dynamic field is by article.

I wonder if I could have a dashboard stats with a quantity of technicians scheduled in the last and in the next week, I'm trying to figure how to change the default open and closed tickets by something like "tickets programed" based in the last datetime dynamic field of each ticket.

Thanks.
