feat(minor): Add signposts for explicit starts

[hassila]

Description

Adding support for per-iteration signposts as requested in https://github.com/ordo-one/package-benchmark/issues/259

How Has This Been Tested?

Manually verified.

Minimal checklist:

• [x] I have performed a self-review of my own code
• [ ] I have added DocC code-level documentation for any public interfaces exported by the package
• [ ] I have added unit and/or integration tests that prove my fix is effective or that my feature works
