Create a microflow that accepts the object with the field that will hold the 1 or 2 value as user input (I'll name the object dataObject).
In the microflow the first action is to create a variable (named: counter) and set this variable to the value of the field (recordNumber) of the dataObject input parameter. So the value will be $dataObject/recordNumber.
Now add a merge activity and after this add the create object activity to create the record to be inserted in the table.
After this action add a change variable action that sets the $counter to $counter-1.
Now add a split after this change variable action that checks if the counter is greater than 0 ($counter > 0) if true this will end the microflow. If false connect this to the merge activity added in the second step.
Now you have a manual for loop in your microflow and the only thing left is to trigger the microflow.
Hope this helps you in finding a solution.
I found an answer with a visual representation of how to achieve what Erwin described:
