Playing certain number of sounds from random container

Question

Is there a way to play a certain number of sounds from the random container?

I see the use case where I would like to play 3 out of 20 sounds that I've loaded into the container in a random order. This is useful when Random Containers are in a Sequence Playlist.

And a follow up question - is it possible, in Wwise, to set a duration for a random container to loop? I'm in a situation where I have a Sequence Container which has 3 random containers. The first one plays one random sound, then the second one loops for a while and then the third one plays a random sound. Apart from interrupting the second random container from code is there a way to do it through Wwise?

Thanks!
