Support pagination configuration

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

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

**Priority**: Low/Medium

No files, tests, or entry points are named. First reconcile whether the work concerns pagination configuration or store import support, then locate the store implementation and its current import or pagination behavior; done should mean the agreed configuration works with sensible defaults and has coverage for the selected behavior.
