Filter whole domain by time

Hello again,
i tried a first project with GSA Spider, and while overall im satisfied, I ran into a problem: on some domains the program spends  A LOT of time. I know there is a checkbox to skip whole domain if nothing found after a long time, but even so, with some domains the program wastes a lot of time. I guess it finds 1 or 2 emails, then spends an eternity searching in the history database.

Is there an option to set a maximum ammout of time the program spends analisyng a domain ?

Thank You.
