It's already been requested, don't know if it will be done though.

Can that be incorporated to the future software update of MM Gold Lifetime?

No, this is not possible.

Hi there! I've recently updated my MM gold lifetime version to the latest one. but i would like to ask if there is a feature to alter/edit/change or customise a songs equalizer setting using MM to my own before uploading it to my device (or to any presets...if any) like what i can do with iTunes?

if so, please may i know how?

Thanks.
