In automix mode, add possibility to exclude one or more transition methods

Good day!

I would like to suggest to add the possibility to exclude one or more transition methods for automix mode, auto transition. Currently you can either select auto, which selects between all transition options or select one transition method that is always used.
I.e. use auto but additionally exclude one or more transition options so that they will never be used.

I think the echo transition for techno styles is hideous but I would still like the variation of the other options.

Kind regards, Bart.
