Prompt At Print Time Follow

I am cutting over from a very old version of Bartender and have go everything organised except i cant find the field "prompt at print time". This used to be a field in the old version. Basically it is connected to a sql database and at the time of printing you type in the product item. This then matches to the same value in the sql table and returns that value plus two other fields. i have the desired database fields added to the label but dont know how to set the item field to prompt at print time.

Help greatly appreciated.

Thanks
