It should be possible with a custom data field in the gasket table and the long descriptions schema updated accordingly
This is what I do, as I want it in the body of the description and not at the end. As far as I know, the 'R' character is hard coded.
Well, a hard code in the software would make sense, because there is nothing that I am doing to invoke it.
I'll experiment with deleting that field and creating my own and see what happens.
