Adding timestamp to custom profile property

Hi,

I’m creating a campaign that will contain buttons allowing subscribers to self-segment themselves. When they click the button, it will create a specific custom profile property for them. 

Is there any way to have this timestamped? Let me give an example for clarity’s sake.

Let’s say I am asking them to self-segment based on age. They can choose 20, 21 or 22. I’d like this to be timestamped so that in the future, I know if they have a profile property saying age 20 in 2024, they will be age 24 in 2028.

Is there any way to do this?

Thank you!
