How to access signed-in user in Data view in the builder?

Was working on a Proof of Concept to roll out user-specific discount codes, and therefore, final prices at check out.

Is there a way to create a column in the Data view that simply outputs the logged-in user’s email address, and also be user-specific?

I was wondering if it could be done via ‘Single Value’, for a signed-in user, and be user-specific.

Would probably need more information on what you are trying to do, but you could have a sheet that contains and email address. Then use a relation and lookup of some sort to get a list of matching emails in that other sheet. You can then filter out discounted items if email in lookup is signed in user. Again, would probably need more information.
