SAP200 api Matlab Eurocode SetPreferences

I am using SAP2000 OAPI in matlab with the help of the SM Toolbox and the CSI documentation (written for Visual basic).

But neither of them seem to have a command for setting preferences about the framing type of my structure choosing DCL-MRF (ductility class low - moment resisting frames) and changing the behaviour factor q.

So I was able to generate ductility class high and medium but could not find the ductility class low indice as it is maybe directly connected with the number of the behaviour factor.

The actual syntax should look maybe something like this:

"ret = Eurocode_3_2005.SetPreference(indice,indice);"

Anyone with further information?
