two base paths in repo (backend/cloud and backend/edge) with different configs and manifest

      - uses: googleapis/release-please-action@main # googleapis/release-please-action@v4
        id: release
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          config-file: backend/edge/release-please-config-backend-edge.json
          manifest-file: backend/edge/release-please-manifest-backend-edge.json

      - uses: googleapis/release-please-action@main # googleapis/release-please-action@v4
        id: release
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          config-file: backend/cloud/release-please-config-backend-edge.json
          manifest-file: backend/cloud/release-please-manifest-backend-edge.json

- Any error messages you're getting

Release PR are being overriden when action is triggered as both configuration uses the same branch release-please--branches--master. Would it be possible to use different configs with diferent PR branches but keeping same target branch?
