W810i play pause feature?

hello people, i was just wondering if theres a way to get the play/pause feature from the w810i (where you press the button on the side to play and pause) to work on other walkmans like m w880i for example because the button on the side of it only brings up the walkman 2.0. is this possible?:confused:

i think you can do this with some elfs. but i am not sure whether there is an elf available for ur requirement. ;)
