Resolve: Fusion comp before and after colorgrading

Resolve (15) now has Fusion comps rendered before the color page. Is there also a way to have a Fusion comp áfter grading? For example, 4 graded footage clips that pipe into a 3D motiongraphic comp, resulting in 1 clip? Cause some cases require graded footage to be piped into VFX; so a MediaIn node, that refers to a graded shot on the timeline. (Now of course possible with rendering out a grading and importing the clip, but would be nice to have this without prerendering)
