Using include inputs for include rules

Missing possibility using include inputs for include rules.

Example

Small example, which is not working:

spec:
    inputs:
        testDir:
            type: string
            default: .gitlab-ci
        projectDir:
            type: string
            default: .
---
include:
    - local: $[[ inputs.testDir ]]/compose/*.yml
      rules:
          - exists:
                - $[[ inputs.projectDir ]]/compose.yaml
