Accessing RGB layers in multi-layer EXRs?

Perhaps some Resolve EXR maester can answer this:
There does not appear to be any way to access more than one (base) RGB layer. Any other RGB layers can only be brought into a node as a matte. If indeed this is so, it limits the EXR workflow to alpha channels.
Can someone confirm that this is so?
