Social Media Content Approval?

Hello all:

Our Houston-based nonprofit is integrating Adobe-based products into our communications streams. We love the social media content scheduling functions of Adobe Express. The only issues we are having with it are: (1) inviting callaborators on social media captions, and (2) content approval. 

So, for instance, if one of our interns creates a social media post on Adobe Express, I would like someone on organizational payroll to preview and approve the content before its actually scheduled. I know collaborators can be invited to edit individual files before they're published to SM, but that does not appear to include any captions or text accompanying the file in the post. Additionally, even if we use the same account, it does not appear as though a draft of a post can be created by an intern and scheduled later on, after it's been reviewed and approved.

Is there a work around for this?

Thanks!
