There are many threads on this issue and at some point a TID will likely be made if it does not already exist, but I thought I would post some updates.
It appears work is currently being done on upgrading the ZCM Linux Kernel used for Imaging to SLES 12, which is expect to allow ZCM to support eMMC Drives.

I do not have an ETA, but if I had to make a wild guess it would be the Oct/Nov timeframe.
These dates did not come from development by any means, I'm just trying to eliminate folks suspect it may be next week or Q4 2020.
