Djm s9 individual channel modes

Not sure if the last questioned got closed so I am bring it forward again for review.

Can you guys not just bring out a mapping or update that allows for indidual channel modes. That is a complete waste of time if u have to map it. As it limits what one side can do to the mapped functions. Like if you press sampler fx at same time as hot cue on channel one. That could bring up hot cue in just that channel? And sampler fx channel 2 at same time as roll could bring up roll on channel 2, I would prefer the spare page of mapping could be used for unique functions that differentiates mixer from competions not to have to use it for the basics!!!
Can you please confirm if this is going to be limitation of this mixer or if engineering will fix it
Kind regards
