Ignore parameter for transition API


is it possible to get from the API the transitions with ignoring a parameter?
I have set the parameter that i want to be ignored in the global list but that doesn’t change the fact that the API is returning the urls with the parameter. The problem is that i can’t get all the following websites this way because they are way to many.

Alternatively i am thinking about using a DB query instead the API and then remove the parameter myself.

On a related topic: Is it possible to make piwik ignore a parameter for the time before it gets set? My archive data still doesn’t ignore the parameter.

Thanks in advance
