Exclude market.yandex.ru from sites source

I connect my site to yandex.market.ru

It the confuse of my statistic “source from sites”

yandex.market.ru - that similar as marketing compaign. That no external site, but it the compaign.

How to exclude some sites from statistic of sources from sites?

When a visitor comes from yandex.market.ru does it mean they are coming via a Paid Yandex Campaign ?
Maybe we could automatically classify the visitor as a Yandex Paid visit ?
