Collectible Card Game Headquarters

I like to play Commander games with randomized decks, but I would like to limit the generated decks to only contain cards from certain sets - is this possible to do somehow? I only see options to generate based on certain formats like Commander/Tiny Leaders, but I might be overlooking something.

It would be very nice to have random decks generated with these kind of filters.
For exemple, if I want to play against a Limited Edition Alpha Red deck, I could just generate a random deck using the color red filter and the Alpha Set filter. Maybe something like the sealed decks are made, but with a set pool, defined by the user.
