[CONNECT u13] Parametric Cell - Variable to control a nested cells origin?

Does anyone know if it is possible to apply variables to control the position of a parametric cell that is nested within another parametric cell? I couldn't get it to work unfortunately it appears to be fixed in it's position once placed. Additionally it seems it may not be possible to link a variable to the cell origin?

I guess one solution would be to create the variables to move all of the geometry within the nested cell itself, however it would be a lot simpler (less constraints required) if this could be achieved within the main cell. Has anyone found any methods to achieve this within the main cell?

Thanks,
