Changine linetypes of objects in Microstation XM Powerdraft edition

Hi,

I have a drawing that was created in AutoCAD. When saved as dgn it retains some linetypes from AutoCAD such as Continuous and DGN Style 2. I would like to select these objects and change their linetype. For example, select everything with a Continuous linetype and change them to linetype 0. Then select everything with linetype DGN Style 2 and change them to linetype 2, etc.

Is this possible using VBA? Can somebody help? My knowledge of VBA is very very limited

Many thanks in advance for your help
