Dynamically move sidebox depending on page

[RFree190]

Is there a way to move a sidebox from the right to the left depending on the page the user is on?
I'd like to turn off the right column for certain pages, but would like to swap one sidebox from the right to the left when the right column is off.

Thanks!

You can alter which side columns show on certain pages but I know of no way to move from right to left only on certain pages
