How do I link a new 3D PCB version to an exiting 2D PCB which is already linked to an older 3D PCB?

I created a PCB sketch in my product assembly then used that sketch to create a 3D PCB using "create PCB". I then linked that 3D PCB to the 2D, placed and routed the PCB. We then made changes to the product and now need to update the PCB to reflect the minor changes. I am not able to make the necessary changes to the PCB shape by editing the 3D PCB, for example I cannot extrude a new slot using the 3D PCB editor, nor can I extrude a new slot in the 3D PCB using edit in place in the assembly. I am thinking I need to unlink the prior 3D file and relink the current 3D file to the 2D. How do I do this? What is the best way to new push PCB (outline) changes to an existing 2D?

@fgauthierZ3CZG , you don't need to unlink to change the board shape. If you right click on the board node on the timeline, you will see two commands: "Edit Sketch" and "Edit Board".

If you click "Edit Sketch", you will enter the sketch environment. As you can see from the commands in the toolbar, in this environment you can create or change the geometries in the sketch:

Using "Edit Board", you can select or change different parts of the sketch to build the pcb.
