Using Groups to specify text/images

I am using Groups to “compartmentalize” a site where different companies can request products specific to their organization. Members of groups (companies) can only see their own products.

I’d like to know if there is a way to use Group membership to specify an image (logo) to display at the header area of pages. In essence I’m looking to simulate using different themes for different groups.

I can use WP Toolkit and Beaver Builder to do this on a PER USER basis, but I would much prefer to somehow use Group membership to do it since there are many users per group.
