How to make a report BY CITIES in Bitrix24?

Question

Bitrix24

Good day to all!
Tell me who knows and knows in this matter.
I have an account in the Bitrix24 system. We have been doing deals and clients there for several years.
This year there was a desire to make analytics of transactions BY CITIES .
It is easy to understand which deal came from which city, or at least a summary of Clients - who is from which city.
This custom field "city" exists both in the deal and in the clients.
But it turned out that such a simple action is not possible in Bitrix24 reports. It seemed very strange to me.
Is it really not possible to make such a filter, or have I missed something??
