Can we have pre-defined /admin defined tags and community level pre-defined/admin defined labels?

Hi,

In Community Admin, we can only define admin defined labels at Board level, but as per our requirement we want to have community level labels, so how can we do this??

In Community Admin, we cannot see any option for defining admin defined tags, which are not created from posts, so is there any such option or way we can have predefined tags which are not created from the posts creation/edit/replies???

Thanks
