Increase Time before sever shuts down when no one is online

Hi aternos Team, when we start up our servers it gives us 5:00 mins to get on before it shuts down, it would be most appreciated if you could increase the time. like 8:00 or 10:00 mins before it shuts down, many times i had to restart my launcher after i started up my server and by the time i get back on the server is offline
