[Orgmode] Subtree exporting to different LaTeX_CLASS

[JBash]

Hi,

A question about exporting:

Is it possible to export two different subtrees in the same file to a different class?  There are cases where it would be nice to be able to generate a document (say an article) from a single subtree in a file, and have other subtrees that contain short presentations that could be exported quickly to beamer, for example.  Currently, the exporter seems to find the first #+LaTeX_CLASS in the file and use that for the entire file export, as well as exporting any subtree in the file, even if you define a separate LaTeX_CLASS under a specific subtree.  I have looked into using export OPTIONS in subtrees for this, but have not hit on the right combination.  Is this possible?

Thanks,
Jerry
