Merge/stripe/span eMMC and sd card space?

Hi,

Is there a way to combine the space on the eMMC with the space on the sd card? Right now I see my eMMC as C: and my sdcard as D:. I’d like to merge both as C: if possible. I’ve been trying this in Windows and it for some reason won’t span properly. I have noticed that it marks my D: drive as MBR and C: is GPT so I imagine that has something to do with it but I can’t get it to change.

Anyone?
