i like it it very informative. i like that it shows next steps. just to note about the dismantle of caravans it doesnt show if the employee can drive a truck etc

can employee's only have 3 ride experience in building and dismantling? for example if an employee already has 3 but starts learning a different style of ride will the new ride overide the previous if he gets above the level of the previous ride or will it always stay the same 3 style of rides they are trained up for?
