I'm looking at running my backtests with slight changes in parameters and would like to be able to categorize them in, for instance, different directories to make it easier to find them. Is there some way to do this or are they only ordered by most recent results first?

Also, I have a number of old backtests I no longer need, either because they were runtime erros or I was testing simple functions and there's no important data in them for me. Is there a quick way to delete a set of Results I no longer need, other than manually removing each and every individual one?
