Is it possible to append the community title automatically to every posts, discussions, questions?

Hi Imtiaz,

There's no way to achieve this natively as of now. If only admins are going to post, you can use API Calls to include community title in all content types by typing it. Otherwise, you can use Zapier as well to automate it however if users are going to post as well, it might not work out.
