Change the numbers of models in the fit axle

Change the amount of models already in the list.
So I can change to what the custumors want instead of having to delete the whole list and put it back in.
Just a + and - function.

Thats a cool Idea, also, when you select a new model to add, it would be nice if it would put a 1 in there by default, right now it only works on the first add. Not that I oppose typing, just would be nice to auto fill

agree on both those ideas

To add: If a model is put already in the list, mark it of remove it from the list or sort the list always on ‘ABC’. Its hard to find the good model in a long list one after one.
