I would like to know if the CamkES has support for wait on multiple signal events ?

I need to wait for 3 different events (say write, read and timer), 

I need to wait until one of these events occur. As soon as I get an event, I need to call a common function. I cannot use emitter/consumer signal events  concept of CamKES  here as it allows only one to one connection and not many to one connection. 

So in other words a single consumer_wait()  for 3 different emitter events is not possible in CamkES. 

Any suggestions how can this be achieved using CamkES?
