Add support for querying and visiting sinks

Hi,
I would need to allow my application to provide to the end user with a dynamic control on sinks configured in settings file (typically, change the filtering at runtime).
For that, I would need to have to list of the configured sinks, but from my searches results on the web, it looks like there is no such a support.

Would it be possible to add the support for querying and visiting the sinks?
If not, what alternative solution would you suggest (if possible, without having to reimplement setup file parser)?

Thanx in advance
