How to ignore GET parameters by Yandex.Metrica?

Question

In contact with

I put Metrica on the iFrame page of the VKontakte application, where each request goes with several GET parameters from VK - user id, session hash, and others.
Metrica believes that each combination of these parameters is a unique login page, and the report turns out to be complete nonsense.
How to configure Yandex.Metrica to ignore certain, or all, GET parameters?

Answer 1

I figured it out: in the counter settings on the Metrics page there is a tab called "Filters" (metrika.yandex.ru/XXXXXX?#tab=filters) , where in the "Operations" section you can drop certain GET parameters from the collection one by one, or even all at once - Exactly what I was looking for!
