Many tasks repeat quarterly, yet Asana does not offer this period of time under “set to repeat” feature. Nor does this feature offer a custom repeat period longer than 30 days. By adding periods of “every other month” and “quarterly” and “6 months” to the “set to repeat” options, you would solve this problem.
Could you use every 3 months in lieu of quarterly?
Yes, certainly! I didn’t realize it would provide an additional interval
option once I choose “Monthly” (it’s not visible until afterward). Thanks!
