Reaper render multichannel 5.1 for video editing

[Musiccreator]

I am created sampling music in 5.1 format in Reaper. However, I do not know how import the multitracks for further work with Da Vinci Resolve, so that in the editing video I could already work with the multitrack.
I have over 20 parts in my daw, this is a full symphony orchestra and each part has six channels for 5.1
as a result, after rendering, I have dozens of multitracks but I don't know how to transfer them to theDa Vinci Resolve video editing station. I would be grateful for your advice.
