How to handle and cull raw and jpg as one on lightroom mobile?

iˋm new to lightroom, and simply can't find how to set up lightroom mobile (on android) for how i want to use it.
i usually work with the raw files, but occasionally use the unedited jpg. therfore i want to import both versions, and during culling handle them together with only seeing each image once (not twice, as raw then as jpg).  then later being able to either edit the chosen raw or access the according jpg (e.g. by moving the chosen ones to another folder, or deleting the culled ones).

what setting do i need to apply for this, and where do i find it? big thanks!
