How to make your own filtering in the Bitrix admin panel?

Question

1C-Bitrix

Good afternoon! Such a question, there is a site with real estate objects, there is an IB in which all these objects, it is necessary that certain users see only the objects assigned to them with a certain status, i.e. PROPERTY_USER = 35, PROPERTY_STATUS = 3 . The regular filter in the admin panel can be removed, and these users should not see each other's objects. As I understand it, this is implemented at the level of infoblock events, but how can I write this in init.php ?

Pay attention to the events of the administrative section: https://dev.1c-bitrix.ru/api_help/main/events/onad...
Before displaying the list of elements, you can filter by the required properties.
The same goes for the edit page.
It's all in theory. You need to watch events and received data.
