Is it possible to adjust a ruleset from the suborg level on the repo level? #678

I have a suborg which defines a ruleset that contains a rule that requires PRs of at least 2 reviewers.

rulesets:
 - name: "Suborg PR"
 target: branch
 enforcement: active
 conditions:
 ref_name:
 include: ["refs/heads/main"]
 exclude: []
 rules:
 - type: pull_request
 parameters:
 dismiss_stale_reviews_on_push: true
 require_code_owner_review: true
 require_last_push_approval: true
 required_approving_review_count: 2
 required_review_thread_resolution: true

Is it possible to adapt the ruleset so that only one reviewer is required for certain repos?

I tried to define a ruleset for a specific repo with the same name "Suborg PR", but then I get a validation error. And I would assume that if I create another ruleset with a different name on the repo level that both rulesets are created and that the more restricitve rule with 2 required reviewers is still applied.
