Add configuration options for import

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

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

**Priority**: Low/Medium

Start by locating the store and import entry points in the repository and read how imported data is currently selected. Determine which filtering options and sensible defaults are required, then verify that configuration is honored during import and that existing behavior remains unchanged.
