PowerCivil for Finland v8i, changing components in cells?

Hi Bentley and the forum members,

We are using PowerCivil for Finland V8i (SELECTseries3) and would like to ask about the possibility to change the size of the components of a 3D cell. Is it possible to change the components of an already created cell when placing it in a drawing/model? We know that it is possible to alter the xyz scales of a cell but then it stretches the whole object. Eg. we would like to have a single streetlight cell where you could select the height of the light pole, the diameter/radius of the light pole and the length of the light arm when placing the cell. So instead of having 10 different cells for streetlighting with different height light poles we could have just one cell where we could change the size of the components. Can this be done with PowerCivil?

Many thanks in advance!

Sari
