Add configuration options for import

**Description**
Currently lib lacks proper pagination support.

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

**Priority**: Low/Medium

Start by locating the import path under lib and tracing how it currently handles pagination. Confirm where configuration is defined and how imports are tested; done means pagination is configurable with sensible defaults and the existing import behavior remains covered.
