Toggle radio senders through knx button

Hello,
i have a knx installation with home assistant as my logic engine. In my bathroom i have a sonos device and want to change my radio senders through a button on my knx.

In home assistant i use the sonos integration combined with the media player. My knx button can send 1 bit (1 oder 0) to my home assistant.
Any ideas, how i could toggle my radios senders? ( it would be great to configure a list of 3 or 4 senders and home assistantshould toggle if someone presses the button.
