room position in calendar

[Wira3]

Please HELP   ....  I have 6 rooms listed in my calendar, but I want to change their position to refect the same position in my Channel manager page. 
I have searched high and dry in the settings, to alter their position but to no avail.

There is no sorting option in the multicalender (as there is one in the overview of listings). It has only a filter.
