Eliminating the extraction of unused devices

I have been experimenting with creating an extraction deck and I have came across the following problem:


I know that we can eliminate unused devices in extract and LVS with the command:


LVS Filter Unused Option (or device)


But, this is specific for LVS.


My question is:


How can I prevent the extraction of unused devices strictly and only through the extraction ruleset? I basically have a semi-custom design with an array of devices and only wish to extract the used ones only to a netlist.


Thanks in advance.
