Changing Imposition File via javascript?

[brew]

Is there a way to change the imposition file in javascript?
The reason I'm asking is because I have logic built to determine which imposition file I should be using for output, but I can't figure out a way to modify the imposition file on the fly.

Thanks in advance.

No, the imposition file cannot be changed in a rule.

If you're using FusionPro Server, you can change the imposition file name in the CFG (job) file. Otherwise, you have to change the file on the Imposition tab of the Composition Settings dialog in FP Desktop.

Unfortunately, this option is not supported in FusionPro.

Any chance of writing out to an imposition file on a OnJobStart or something like that?
At what point in composition is the imposition file read?
