Yes, any nudge, whether created as a custom nudge or from a template, can be set to be recurring.
It’s important that recurring nudges are the nudge (or task) itself reposting, not the reminders for a particular nudge. Recurring nudges are great for assigning something to a client that needs to be done every quarter (like pay their estimated taxes) or every year (like fund their ROTH IRA).
Recurring options include weekly, every other week, monthly, every 2, 3, 4, or 6th month, yearly, or every 2,3,4,5, or 6th year.
