Customising pages process

Hi,
I find that piwik is really great.
I am wondering how to get some more customization in it.
Say I have
Action/Pages

object/action1?parameter1=1&parameter2=2
object/action1?parameter1=2&parameter2=2
object/action1?parameter1=3&parameter2=10
object/action1?parameter1=4&parameter2=1

piwik is already grouping on object.
But I would like counts to be grouped on actionx.
to have
object 10
action1 7
parameter1…
action2 1
action3 2
I have seen no parameter to allow that.
And I would like to see if other ppl encounter that, how they did, and if there would be some pointers.
Sorry if it is a “newcomer” question. I saw no search on the forum. So this question may have already been dealt with.

You can use


piwikTracker.setDocumentTitle("Your custom / category / hierarchy");

Hi.
I tried the following :
piwikTracker.SetDocumentTitle(document.URL.replace(new RegExp("[?=&]",“g”),’/’))
ou
piwikTracker.doPageTrackView(document.URL.replace(new RegExp("[?=&]",“g”),’/’))
ou
piwikTracker.trackPageView(document.baseURI.replace(new RegExp("[?=&]",“g”),’/’));

But none of those techniques allowed me to get the expected results.
Grouping Action Pages on basename (allowing to get some partial results on how many pages were visited.)
say :
search
detail
sendbasket

is there something I miss ?
Is there a way to track the message sent and see where the problem lies ?
