Feature request - Change starting difficulty for puzzle streak

I think it would be a good idea to be able to change the starting difficulty of puzzle streak (and possibly the other puzzle formats too).

Currently it starts around 900. I think it would be good if there was the option of starting at a harder point, such as having different difficulty levels, or being able to select the rating difficulty of the starting puzzle.

That would mess up puzzle streak scores because people could have much lower or higher puzzle streaks to share (totally not brag) with their friends.

I would have thought that the only result of this would be lower scores at harder difficulty, as the puzzles would be harder, and the results do not impact anything so they can brag as much as they like (or not) and it wouldn't be any different to how it is now.
