Is there a way to automatically renew an add-on?

I don't make enough calls to justify picking the unlimited calls plan (7$).
However, I would be very happy with the 60 mins for 3$ add-on.
Is there a way to automatically renew this add-on instead of manually buying it every month?
Thanks!

Hopefully not Steven! Just in case you don’t want it anymore!
