It should be possible using scripting. Bruce Bullis can share more details.
An ExtendScript script (.jsx file) or HTML5 panel (which calls ExtendScript) can do that. Please write me directly, and I'll get you a sample script (and panel) which do so.

Reason for not just posting a sample script: There is a way of doing it, that would work, in 7.x. However, there is a much BETTER way of doing it in the version we <ahem> technology-previewed at NAB, which will be generally available, Really Soon Now™. Unless you're very pressed for time, we recommend you wait for the newer better way.
