Subdomain for nonsensitive content for player card


Few months ago my domain was authorized for player cards. But was marked as sensitive per my request. The problem is that not all content posted in cards from this domain is sensitive. But those tweets’ engagement is still effected by different kinds of filtering in twitter.
Since I can filter sensitive and nonsensitive cards on my end. Can I create subdomain (for example and get sensitive flag removed for cards from this subdomain?
If not please let me know the other solutions of this issue.

Thank you .
