Dropper on 2017 BMC FS01

[Oswald]

I have a BMC FS01 XTR DI2 from 2017. I would like to install a dropper post with internal cable, but don't know how to do it.

I know it's possible, because I have seen it on Absalon's bike, and also in this picture from a bike on Ebay:

I need to figure out where to insert the cable into the frame. But also what to do with the internal DI2 battery which is now in the seatpost. Also keeping in mind that I have frame in size small.

Also, is there a seatpost that can be remotely triggered by the Fox DI2 switch? This is the switch:

It has 3 settings that can be programmed thru the software.
I now have 1 - locked, 2 - half open, 3 - open.
If possible I would set 1 - half open seatpost up, 2 - open seatpost up, 3 - open seatpost down.

watching this one... I've been looking for a solution other then Magura Vyron..

I pulled out the bb cups because they need to be replaced. I was hoping to find a hole in the bb shell to insert a dropper remote cable, but there is no hole. Anyone have a clue as to where to insert the cable in the seattube on this frame?

Ouch, there's always AXS if asthetics mean $400 more than external routing.

I went with a Magura Vryon... cheaper then AXS... it's been a game changer so far.
