We Can't use 'pull input' in combine object?

I found 'pull input can't be used in combine object' in the manual.
If so, how can I get the solution about the attached example model?

Two parallel joining lines use one storage queue.

I attach the ex model.

I need help.

Am not sure, if I understood your question correctly!?

If you want to send specific Itemtypes to specific Combiner, you should use one Queue for every Itemtype or even for every Combiner.

If you want to know the content in your Queue it maybe isn´t important to know the ItemType there!? So set it onEntry of your Combiner.
