XF 2.2 Custom User Fields - Change X amount of times within a certain period

[Scratched]

Hi,

Is there a way for users to modify their own custom user fields, but only x amount of times within a set time period? If there is an addon for this too, I would love to know.

E.g. A user can only modify a specified custom user field 5 times in 2 months.

Thanks.
