When you create one cant for each speed scheme it can be difficult, after a couple of changes, to make sure that the cant is set to the same value in each curve. Especially when there are multiple train categories that are allowed to go with different speeds. But in the real track they would all have the same cant applied in the track. Therefore I would like to have the possibility to link multiple speed schemes to each cant. If you do that you would only need one cant table in normal cases, or maybe two if you are in an early stage and need to investigate something - and f there´s a need to modify the cant you can do it in one place.
