How to move symbol origin for only SOME instances

About symbol origins in cadence virtuoso,

I have an old symbol with a messed up origin. It is inconvenient when placing a new instance. However, many schematics use the symbol so if I change the origin using Edit->Origin it will break all existing schematics which use the device. Is there a way to fix the symbol position (to counteract or offset the change) in a schematic hierarchy such that existing schematics don't break?

I don't think this is possible right now - although it did get me thinking about a way we might be able to enhance the tool to allow such a possibility in future.

For now you could create a copy of the symbol (e.g. called "symbolNew") and move the origin on that symbolNew view. Then create new instances using symbolNew rather than symbol...

By the way, an example for such a symbol with an "interesting" origin is the ideal_balun from analogLib.
