Smart way to handle multiple decay modes with DecayHandler
As far as I know, there is no elegant way to handle multiple decay modes of different particles. If I consider e.g. ttbar production and want to have only semi-leptonic decays, one has to start two runs: Either the W+ decays leptonically and the W- hadronically and the other way around. Otherwise the pure hadronic decays will dominate. I think it would be nice to have the possibility to define all kind of decays in one run card, similar as the different process-blocks in the "process" section. Is anything like this planned or maybe even implemented already?
