Parameterized component links

Hi, I asked some moons ago about the possibility to have parameterized component links. I'm not that familiar with pier so my solution to this might be a bit cheesy. I wanted to have for multiple reason the ability to do +mycomponent1|key=value+ to parameterize a component at rendering time. The problem is that the string is parsed to a link and the link has the parameters. So the question is how the component gets notice of these. The last possible call to do I recognized to be PRViewRenderer>>visitInternalLinkEmbed: I added the following to it at the beginning (anObject target isComponent) ifTrue: [ anObject parameters do: [:each| (self context componentAt: anObject target) propertyAt: each key put: each value. ] ]. So I just copy all the parameters over to the component. I found that PRComponent has already properties so I'm using these. Is this feasible to do? Is there a better way to do? Can this be added to pier? I use this for two scenarios: - advising a component what type it should filter - to select a child component from a Magritte container (not done, yet) thanks, Norbert
