Looping a static amount of times only for a few requests

Hey, I'll try to give as many details as I can.

My DataSource is an Excel file. Its purpose is to basically have a payload adjustment for each test case.

Those payloads are then injected into requests.

So the flow structure is:

DataSource

Request X (REST)

Request Y (REST)

DataSink

DataLoop

The DataSink writes requests X&Y IDs responses into the same Excel file.

I need that for each request X response ID there will be a Y response ID (as I described in the table of the original message).

All is fine when I require the loop to go over the entire flow again & again until the DataSource ends.

What I'm missing is setting the loop to run a defined amount of times (while loop), then I could use it 5 times for request X as a nested loop, and a 'big' loop for the entire flow.

Thanks a lot!

Isaac.
