Quick question about scroll background

[handsource-dyko]

I was just wondering, is it possible to change the scroll background of an active scroll without stopping it and restarting it first?  :-\
I'm creating an enviornment trigger (effect that fades the background and changes the music when jack passes it). The trigger works nicely, but I can't seem to change the background plane to a different graph code when the scroll is active. Is it perhaps read-only? The DIV manual says that some fields of scroll structure cannot be altered.

Use your own scroll with processes and you can do with the scroll all that you want...

Too much trouble for a small feature improvement....
