How to update dynamic connector symbol in Solidworks electrical 3D

Please see the attached drawing.

I have inserted two dynamic connector symbols XD2 and XD3.

Wires are connected to all of its pins.

I added an attribute to the connector symbol by configuring the 'Connector configurations management'.

After that when I try to update the connector symbol, this is the message that I am getting.

I do not want to delete the symbol because if I do that, all the wires will re-align and will create a mess. I will also lose the manufacturer parts that are added to the symbol.

Is there any way that I can update the dynamic connector symbol after when it is inserted in a drawing?
