Dynamic task names

We would like to implement a Loop scenario for various numbers of sequential approvals. For instance, based on data/conditions in the form, we may need 1 approval sometimes, but 3 approvals in another case.

Instead of building 3 different Activities, with each of the different approals, we are considering 1 task in a loop. What would be nice would be if we could dynamically change the name of the task (with a variable) so that it could be uniquley identified, instead of using the same task name 3 times.
