I think a way to study verb types would be super useful, since while memorizing them as you go IS an option, for some people like me, remembering if a verb is ichidan or godan can be rather difficult.
We do not have this exact thing, but if you go Manage your Schedules > All schedules, we DO have verb conjugation schedules. You could always choose to just practice those two verb types, and it would effectively be what you're looking to do.
