Calendar Tasks variable time settings.

In the tasks area of calendar creation there needs to have a customizeable time frame menu item. For instance, there is the ability to create a weekly repeat item, but if an item is bi-weekly or bi-monthly, there is no ability to address those types of repeat items. Also, if something needed to have a task scheduled for every other day instead of every day, other software allows every (2) days or however long the period between tasks, but RingCentral does not. Can this be changed to be further customizeable by the user?
