I haven't tried it in a while but I believe it is still the same as in older versions.
The only way I have managed to do it is to restructure the schedule to fit the width of the page.
It will be too long so duplicate it onto another layout page.
Now crop the bottom off the first page.
Crop off the second page the part that you can see on the first page and reposition it.
If it is still too long copy to a third page and crop again.
Here is an old post explaining it.

And this one shows the difference between splitting and restructuring.

There is another post somewhere where I show the cropping and masking but I can't seem to find it at the moment.
