I think check the examples in the "Random data generator" in the App store. There is an example in it you can use for this purpose.
In fact you begin with variable offset = 0 and variable amount = number of recurring entries
Loop over your actions and change offset = offset +1
You loop till offset > amount
I haven't tried this, but I have thought about it. Maybe you can simulate a predefined loop by putting a retrieve action of the object you want to loop over at the end of the microflow, then counting that list, and put an exclusive split behind that which checks if the counted variable >= the number of times you want to loop. If true, end the microflow, if false: start the microflow again using the 'call microflow' action.
I know that you cant loop in your micro-flow except for list of objects. so I have an idea about this:
