Yes ~ M'L' needs to be Loaded on each SD Card that you wish to use with M'L' Functionality.
The path that I would suggest would be to go through All the M'L' Settings that you think you might
be using on a Regular Basis & make any changes that you desire. Then Copy the M'L' Related Items
from that Card back to your computer, copy those items to any additional Cards, put them in your 70D,
Start it up, Do a FirmWare Update (Each Card 1 Time Only) & you're done. Any time that you make any
Changes to any M'L' Settings that you might want on Other Cards, simply copy the "settings" Folder from
the "ML" Folder on that "Changed" Card to the "ML" Folder on the Other Cards & you're Done Again. This
"Settings Copy&Paste" also is very handy when Updates to M'L' become available.
