The tutorial on hashme may be of help.
All cells generated by hashed function calls have the _$#### hash suffix as unique identifier.
In newer Nazca versions (0.5.7 and up) the hashme=True has become optional in de Cell() call.
The hashme decorator does not only check for the cell name, but for the full call profile and it generates a unique cell name based on that (with the hash). You can also manage cell names yourself and simply send or generate a unique cell name every time you call your cell generating function. Hashme does all the work for you in one line with a few characters in case of parametrized cells.
