Prefered Release Group for Anime by default in whitelist

[hergonoway]

Is your feature request related to a problem? Please describe.
Most of the times I add Anime before the first episode is aired, which lead to the problem of adding manually my prefered release groups for each show. (since the list is not yet available)

Describe the solution you'd like
Being able to manage a list of Prefered Release groups which will be added automatically to each Anime show that I add as default whitelisted Release Group. In my case Hi10, HorribleSubs, Commie and few other always publish their hash files in anidb which ensure that'll be able to check the crc over Anidb for archive purpose

Describe alternatives you've considered
do it manually each time

don't know when it'll be handled but being able to mass update whitelists may be an alternative if default whitelist is too much to ask. :)

else why not use the "Save Defaults" already existing mechanism while adding a new show?
