How to add a virtual pin to a symbol without transferring to layout/matching to the footprint

Hi everybody.
I am adding a pin to a Capture symbol in order to feed a stimulus during simulation - the pin is obviously virtual and must not be matched to any pin of the footprint.
(Just to explain, I am using a stimuls to simulate the action of a switch in the PSPICE model)

Is there a way to flag that pin in the symbol so that it does not create net errors for mismatch to the footprint?

I have looked around but found no solution so far.

Thanks

Eddo.

    The netlist is PCB. 
    The NET (tab Tools Create netlist PCB) generated with Capture 25 is (for a dummy schematic with just this component)

    FILE_TYPE=LIBRARY_PARTS;
    pin
    [...]
    'CTRL':
    PIN_NUMBER='(4)';
    PINUSE='UNSPEC';
    end_pin;
    body
    PART_NAME='MTS102';
    JEDEC_TYPE='MTS102';
    VALUE='MTS-102';
    end_body;
    end_primitive;
    END.

    The problem is that pin 4 is being transferred.

    Update to layout fails with message


    #1 ERROR(SPMHNI-191): Device/Symbol check error detected.

    ERROR(SPMHNI-195): Symbol 'MTS102' for device 'MTS102_MTS102_MTS-102' is missing pin '4'.


    Thank you so much for your attention :)

    (I have tried removing the pin number, using 0 as pin number, none of this helped. Pin Ignore does not allow me to associate to the PSPICE model.)
