Builds not triggered on new opened PR with Bitbucket

Is there a specific setting on circle.yml or in the settings to enable this feature.
It looks like it works for github but not for bitbucket.
I’ve enabled Permissive building of fork pull requests but the description says it applies to github, is there something similar you can do with bitbucket? Could you point me in the right doc to implement this?

Thanks

Unfortunately, we currently don’t support building ‘fork PR’s’ for Bitbucket projects.

Is there a roadmap where this feature might be included, do you have an area where the community can request for features like this one?
