Possibility to Loop with multiple read from HashInput in Talend

Question

I want to build a Loop and execute a block multiple times. tLoop1 would be generating rows and tMap1 would be executed tLoop1(times) . I want to reiterate over a set of datarows until all have been processed. I'm aware that it doesn't work with tHashInput2 connected to tHashInput1, since there isn't a possibility to initialise it beforehand.

Any ideas?
