Possible to Append URL Parameters to Opt-In Link?

Interesting.
Basically I am wondering if there is any way I can ‘know’ from the perspective of the default confirmation page which user just confirmed their email?

I mean I guess I could in theory tag them with a purpose built tag that is removed from all contacts after a minute or two.

Therby enabling a query to the api to check which users have the tag. Not perfect but might work for trying to figure out which link the users clicked in order to redirect to an appropriate landing spot.
