Storing external reports in Piwik (no replies)

Hi all,

I read about the possibility to display external data in Piwik reports - this is already great, but I'm wondering if anyone has tried to store these external data reports in the Piwik database?
It seems not so nice to have to connect to the other database every time I want to see the report... The report data I want to display is less dynamic than page visits, something really only worth storing once a day (e.g. total number of registered users on the website, or total content items) - that's why I don't want to push it via the tracking script.

I hope this doesn't sound too silly, I'm new to Piwik, but I'd be grateful if you could share your thoughts - does this sound crazy, or is it worth working on? Are there perhaps some API methods that could be easily adapted for this?

Thanks,
Anna
