Possibilities of inclusion of r10k features in g10k like ignore_branch_prefixes?

[omkarpatil09]

in one of my setup. I have below g10k.yaml file, however the ignore_branch_prefixes feature of r10k does not seem to work with g10k. When I run g10k --config g10k.yaml it simply syncs all the branches and creates corresponding environments. Is there anything I'm doing wrong here or this feature is not present in g10k? If this feature is not there is there any other feature or any plans in the future to add this option?

Also, does purge levels of r10k work with g10k?

g10k.yaml:

---
cachedir: /var/cache/g10k

sources:
  mysource:
    remote: 'https://github.com/puppetlabs/control-repo.git'
    basedir: '/etc/puppetlabs/code/environments'
    ignore_branch_prefixes:
      - 'Marty'
      - 'whitesource'
