How to export only from user accessible catalog

Hello everyone, I've got a Hybris system with a few catalogs for different countries, managed by country admins. Every admin has access only to it's own country catalog but HAC exports components from all catalogs in database.
So what I want to achieve is when admin from country A (with access to catalog A) uses HAC export he should receive only components from catalog A, not B, C, D etc.
Any ideas how can I achieve this? Some kind of restriction? Overriding some services/jobs?

Thanks in advance for any help!
