Breakout room division

Hi Community! My issue is the next one: is it possible to distribute the participants of the meeting in the breakout romms manually and automatically at the same time orto divide some participants beforehand and the rest direct in the meeting automatically? Because we need to have 4 breakout session rooms with 2 defined hostes per each room and  other participants that are divided randomly in order to spend time on this.

Thank you for your answer in advance!
