Customer Alert field report

Hi, we use the alert field in the customer record to state if a customer should get £0.00 carriage fees.

This has happened over a number of year and we now do not know who gets £0.00 carriage fees and we need to audit whether this is still correct.

I would like to generate a report through report designer to include the alert field.

I've been told I cannot do this and I should make a suggestion ideas.

So my idea is to have a customer report with the alert field included.
