Can Reformed Slavic Pagans Request a Great Holy War?

I'm new to the game, playing as Poland. I have reformed the Slavic (pagan) faith. The head of the religion (who is my vassal) has called a Great Holy War on their own already. I'm wondering if it's possible to request one? The targets he seems to pick are not appealing...

More concretely:

(1) Is it possible to request a Great Holy War as a reformed Slavic pagan?

(2) If so, how do I do it?

(3) [somewhat unrelated] Where can I check when the last Great Holy War was called?
