Can piwik update visitor profile with new data?

Hi,

I have use case like this:

User visits url -> during PHP run we use PHP tracker to register events -> just after php run, there is javascript tracker which tracks page views.

I’ve hoped that piwik will pick up additional data (unavailable server-side - like resolution) and add it to user profile, but it’s not happening. Do I have to set some config option for this or this is just not possible with piwik?
