Support filtering configuration

**Description**
Currently helpers lacks proper serialization support.

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

**Priority**: Low/Medium

The issue does not name files, tests, or entry points. Start by locating the helpers and existing configuration and serialization logic, then determine how filtering configuration relates to the proposed serialization support. Done means configurable serialization works with sensible defaults and the relevant behavior is covered by tests.
