Add configuration options for export

**Description**
Currently handlers lacks proper filtering support.

**Proposed solution**
Add configurable filtering with sensible defaults.

**Priority**: Low/Medium

Start by locating the handlers responsible for export and the existing configuration entry points. Read how export behavior is currently selected, then determine where configurable filtering and its defaults belong. Done means export handlers support filtering through configuration with sensible default behavior.
