My primary music streaming services are Tidal and SiriusXM. I have the most popular playlist (tidal) and stations (SiriusXM) set up on buttons on tough panels. My question is, is there a way to change or add buttons dynamically? I already have a Christmas Season variable that controls indoor and outdoor Christmas settings (runs from Nov 1 to Jan 1). I would like to show our favorite Christmas playlists and stations during the Christmas season and then remove them.

Mhh. No real way to add or remove 'buttons'in programming - but you could for example have three experience buttons do something like:

'Classics'

'Upbeat'

'Relaxing'

That would get changed to seasonal music when wanted (ie halloween, christmas, summer, winter) using variables or even just the scheduler (it allows "IF date is between x and y" under programming)

You can use that same variable to change the programming that those buttons actuate. The buttons themselves wouldn't be able to change likely. Maybe you could create a custom scenario button with an extra selection that is only chosen through programming. I have not tried anything like that, so I wouldn't know exactly how to set it up.
