Any way to preserve a property (such as DNP) on parts when doing a replace cache?

I have a design that has a large number of 0 Ohm resistors, and some of them have a property of DNP with a value of DNP on them.  I need to update all these parts with a new library part.  I also need it to add the new properties that are in the new library part, as well as replace the ones that already exist, while preserving the REFDES, which is exactly what replace cache does with the appropriate boxes checked.  But...I'd like it to also preserve the DNP property if it existed on the old symbol.  Any way to do this?  The other option is to do the replace cache, and have to go in and re-add the DNP property to all the replaced components.

Thanks,

Austin
