Product Marketing Sitting on CS Team?

Does anyone have a product marketer sitting on the CS team?  We have a gap in getting needed screenshots and feature release notes in a timely manner so we can update our users as we push app updates.  My thought being this person could be a liaison between dev and CS and also be responsible for updating all of our help center and training materials.  Would love any advice for those who've gone through this or have opted for another path to the same solution.
