There is one solution. It still at testing phase, but we have only positive results so far. the Scheduler may be done by means of Windows Scheduler and our small tool - Send2B.exe. This is small app that send PangoScript command to BEYOND, and you define the command as argument.
As example: Send2B.exe Blackout
If you are interested, let me know, I will provide a link.
Regarding play-list and date/time - we have it in our plans, but with low to medium priority. Send2B exists right now and can be used with various schedulers.
