can I configure spiral sketch? How?

for each configuration should vary the extrusion length = ok feasible
but also the length of the spiral...

How could I do that?

Exit from each function, double-click on propeller/spiral and you will see starting angle and number of revolutions, right-click on number revolutions and "configure quota".
Of course, there must be more than one configuration.
