Possible to add EMMC chip?

I just ordered a couple of the 1GB models without emmc from AliExpress. Do these models have the pads/connections for the emmc, just no module? In other words, is it technically possible to solder an emmc chip onto the board? I’ve looked online for pictures of the 512MB/1GB boards to see if they show this. The pictures I’ve found all seem to have the black square where the emmc is, but I’m not sure if those are just stock photos of a board with emmc.
