Specify different MFE rendering on same publish channel

In a particular module, as a content author, I want the flexibility of specifying how the units (and blocks within) are rendered onto a MFE.

For example, I may want a flat rendering where there is no navigation between the units in a module and it all displays as one page when published OR I may want a ‘layered’ rendering where I can have a side nav menu to navigate between the units.

However, I want that ability within contentful to specify which MFE I am using to publish and so I can publish multiple types of content onto the same web page (destination channel)

I need help to get me started on adding whatever custom field in contentful to specify this multiple rendering option for the same asset (module).
