Hey machieb,
I'm not sure to exactly understand what you're talking about. If you mean a "match transforms" tool, that doesn't exist in Clarisse.
If you want to change the pivot of your object, you can by pressing Insert, and you can snap it (S) on any
surface, but not on vertices.
If you want to snap your object on translate but not change tool to rotate, you can use the Transform Tool (T) which is very useful.
I can recommend you this tutorial for additional layout informations

Cheers,
