Property Welded Parts List adding a property

Hello

I have a problem replacing materials with Selectmaterial. When I change materials, custom properties do not change due to a known SOLIDWORKS bug. So I'm thinking of using the "delete" function of the smartproperties, and adding my new material to the soldered list. the delete function removes all properties, and I would like to be able to return a property called "LENGTH", with the value "LENGTH@@@TUBE CAR 40X40X1.5 INOX<2>@F0-01837-0. SLDPRT".

in the same way that I see the "QUANTITY" property reappear on its own with its value in formula every time I apply my material.

Kind regards.
