Dynamically change value of custom field added in User registration form

Hi!

So I have added an ACF custom field ( text input) to my User registration form, and I want to dynamically give it the value of the page url the current user is registering from.

I only want to save that value for the specific user that is registering and the display it in the Dashboard-> Users -> created a new column called “registered from page” ( using Admin Column Pro)
Would it be possible to save that value from the custom field in the user register form only for the specific user?

Thank you in advance!
