The DEVICE needs a way of supporting (calibre) series.
Series is not a DC (dublin core) metadata value
I create a 'collection' on my K4nt using the Kindle Collections plugin. Unfortunate (for us), these device manufacturers do everything in their power to thwart users making up for limitations.
If you have a Android or IOS device, Calibre Companion (next forum down) is well integrated with Calibre and makes use of Calibre's metadate.
