I bring my raw footage into Resolve first. Do a little rough cut of the shots I know I want to use -- grade them in Resolve -- export them as individual graded ProResHQ clips (making sure to have handles) -- and then use those new clips as my raw footage in Premiere for the edit. Works great with no round tripping needed and I don't have to look at ungraded S-LOG during the edit. And if decide to make a grading change, I just go back to Resolve, make the change, export with the clip(s) using the same name to the same location, and Premiere automatically updates with the new version. It might not work for a documentary with a 100:1 shooting ratio, but it works great for me.
This is the workflow I used with Assimilate Scratch as well. Only difference is I did it on all the raw footage. Took a little longer to process but once I had it I didn't have to worry about it.
Can also work in reverse for the OP where he can remove the slow motion effects from Premiere from each clip and send to Resolve just the cuts. Do the grade in Resolve and then render each clip as a new set of source clips to replace the material in the Premiere project. Then apply the slow motion again in Premiere.
The movement of clips between programs should be just that, the clips. If the OP wants to use Premiere thats fine but then he just needs a better workflow where he either grades the clips first and then edits in Premiere or just edits a rough in Premiere first, sends to Resolve and then finishes in Premiere. Either way expecting effects to move over just isn't going to happen. Every program handles slow motion differently and while on the surface it may seem like a simple action it really is not.
