Is it possible to extend simultaneous turns after 10 in-game months? Auto-translated

My friends and I usually play maps of the largest sizes and try to explore them thoroughly, rather than trying to win as quickly as possible. Therefore, the games take a long time, sometimes up to 15-20 in-game months. However, simultaneous turns only work for the first 10 months, and after they are disabled, the game slows down significantly, even with two players, let alone three or four. Is there a way to remove the limit on the number of simultaneous turns in the online lobby or increase the limit of their operation?
