Meshlab- Is there a easy way to set may coordinates system in reference to a single point?

Question

I am using meshlab to update two stl files which a later use in a CFD software(openfoam). Now I have to change mine coordinate systems of both stl files which I would like to set in according to a point of the stl files. I know there should be a easy way to achieve that, but did not manage to find it so far....

Thanks for you help;)
