Yandex.Maps: a balloon for objects that are almost at the same point?

Question

Yandex

What is the best way to make a balloon for objects that are practically at the same point, i.e. with a distance less than the clustering distance?
Example: all apartments in one building, all organizations in one office building.
I saw only such an implementation maps.1cs.su/controller.html?mode=5
Is this the only option?

Answer 1

That's it, I found the answer to the question
api.yandex.ru/maps/jsbox/cluster_balloon_layout in the Yandex.Maps sandbox

Answer 2

1) Increase the clustering distance, then a single balloon can be used for them. The cluster icon can be changed depending on the number of objects.
2) Reduce the object icons themselves.
