How to filter related model list by another field?

Question

Django

Good day!
I have a Core app with a StandardModel that is linked to another app's model by the phobj field.
In the admin panel, when adding a StandardModel object, the connection to the PhotoObject is selected from the list (see picture).
The PhotoObject has a parent Catalog object.
Question: how to filter the PhotoObject list by the Catalog model in the admin panel?
And the second: how to display pictures in the list?
______________
Thanks!
