This is the sample model combinertest.fsm that I've attached. I want to use operators on process which has more than 1 content for processing, however it will get messed up, such as being blocked. So I resort to using combiner to combine them first, before going to the processor. However, in the initial model(without combiner), the processor takes in max. number of 16 items, it can take in lesser number of items too, less than or equal to 16. Then the problem occurs, the combiner only allows a fixed number. Can I make the combiner's target quantity to depend on the number of inputs from the queue before? Like, after a period of time, the queue releases the number of items if it has not yet reached 16.
