Moving a trailer mod to a different slot in trailer dealership

[LAFAYET47]

Hello, I would like to move a trailer mod to a different trailer brand in trailer dealership. How could I do this?

I have tried with the following:

rename the trailer folder to the same brand name as the desired one in def/vehicle/trailer/trailer_dealer

change the icon of the previous trailer to the desired trailer brand in material/ui/trailer_brand_logo

But it still doesnt work, I know something else must be done at def editing but not sure what files do I need to change. Anyone can help me please?
