Is it possible and how to connect the Target Call in Yandex.Metrica to individual pages of the site?

Question

Yandex.Metrica

Hello!
The task is to separately account for incoming traffic in order to evaluate the effectiveness of an advertising company in Ya.Direct.
What you need to get as a result: a report on an incoming call indicating which ad/request/key the potential client called.
Theoretically, this can be done using the "Target Call" service from Ya. Metrika, but the question is whether this can be implemented not for the entire domain, but for just a few pages that are planned to be measured?

Put the number substitution script only on the necessary pages.
