Deleting Schematic instance and instantiating another device on the same origin

Dear All,

I am looking to do the following thing using SKILL

1. Open a schematic and look for a specific instance.

2. Delete the instance.

3. Instantiate another cell at the same origin (Both the symbols match in pin locations.)

I am not able to identify, how I can get the origin of the original instance before deleting it. Any kind of help is much appreciated.

Please help!

Thanks,

Vijay
