Ultra pcell - pcell with variable of pcell in it.

Hi All,

Is there possible for us to create a ultra pcell where the pcell within the pcell is a variable, not fixed.

Example: I have a dummy pcell which is ultra pcell, and i want to make it flexible enough to have n number of dummy1 pcell in it, with different CDF param value. If it is possible, it will be great if you could share some example,

Thanks.
