How to associate an extracted netlist of a subckt to the symbol view in schematic editor.

Dear All,

I am using Calibre ( mentor Graphics). It creates the spectre Netlist and calibre view for PEX.

However, claibre view creation takes a lot of time unlike its spectre Netlist.

The spectre netlist it creates in a file like xyz.pex.netlist.

The format is as below:-

simulator lang=spectre
include "SUBCKT_BLOCK.pex.netlist.pex"
subckt SUBCKT_BLOCK (  DVDD DVSS A B C D E \
 F )

        .................................

............................................

............the sub ckt netlist body .............

........................................................

include "SUBCKT_BLOCK.pex.netlist.DIV_BY_4_WITH_GRID.pxi"
//
ends SUBCKT_BLOCK
//
//

Is it possible to associate this netlist to the corresponding subckt symbol used in the bigger ckt block the schematic editor so that the created netlist will have the above sub-ckt netlist in the output netlist of the bigger ckt block ?

Kind Regards,
