/set %list %list TOKEN
or
/help $addtok
But like I mentioned previously, it doesn't matter what type of storage you use.
/help /writeini
/help /write
/help variables
/help $addtok
/help hash tables
As for speeding up the process, I'd imagine you could use the same %list and pull info from that instead, should be quicker than pulling values from $chan(), by how much I can't tell you though.
