Node Administrator determined by Taxonomy_access

Hello,

Thank you for a very powerful and feature rich program. While I am deriving much benefit from Drupal, I find that the one layer of administration is a bit of a limitation. By this I mean that if a user has Administer Node access, then they can administer ALL nodes. Also, only roles with Administer Nodes can publish/approve content.

What I would like to see is a second level of administration that would allow another role to administer content based on the Taxonomy_access. By this I mean that is Role 1 is permission assigned to Taxonomy 1, and Role 2 is assigned permission to taxonomy 2, then Role 1 could approve content submitted for taxonomy 1 but not taxonomy 2, and Role 2 could approve content submitted to taxonomy 2 but not to taxonomy 1. My understanding is that only the over-all Administer Nodes role could approve content equally to both these taxonomies.

If this has already been done, then please direct me to the appropriate module or instructions on how to achieve it.

I am using 4.7.0 and Taxonomy Access. I will also try OG to see if that provides what I am looking for.

Thanks in advance.
