Xmas Market and the cooldown period (add another market to merchant for gems)

Even with 4 Xmas Markets, the split with the cooldown doesn't realistically allow me to manage 2 fully upgraded markets. The split being 5 hours 14 mins means even I start one at 6.30am and the 2nd at 11.44am, by the time i come to buff the 2nd market in the evening it will be way past 11pm... doesn't leave much time to sleep does it?

Having a 5th would reduce the cooldown so I could realistically run the two at decent times of the day..

Yeah add one to merchant,nigh on impossible to run two without a very early or late intervention.

Doesn't matter that you can't upgrade it as it will be cooldown only anyway.

An alternative suggestion would be to add "charges" per market place, you could save up the buffs and use them at the same time then. Eg 4 markets you could use 2 buffs every ~12 hours rather than being forced to use 1 every 6 hours.
