Copy a protocol downsampling the number of vertices

I have imported the anatomy for all my subjects and checked/adjusted all the fiducial points manually using the MRI viewer. Unfortunately, I did that with the 15000 vertices for the cortex surface and I actually "only" need 5000 vertices.
I would therefore want to kind of copy the first protocol in a second protocol but downsampling the number of vertices.

you can just downsample the surfaces without changing any other data.
you can just right-click on the surface and then downsample it.
15000 is the recommended number if you want to perform source localization.
