Dual extruder (not quick change)

I thought I read somewhere that the forthcoming dual extruder head will be available for the existing Snapmaker 2.0 ( A350) . Is this correct? Will this be an ordering option?

Pre-order starts tomorrow, September 27, 2022.

i’m probably explaining this badly but I was trying to find out whether the slider on snap er 2.0 can provide the quick swap option? if not, how?
