Sometimes your merge tag information can be the same for every recipient in a certain mailing, but can vary depending on the mailing itself. 

For example, you might have a document which is the same every time you use it, except you need to change one or two things, like the location and time if it was an appointment letter. 

You can place merge tag in your document for <> and <> in exactly the same way as described, but not have a column with this information in on your spreadsheet. (see ‘Add new account merge tag’ under the Library section for instructions on input). 

Every time you use that document in a mailing, you will be prompted to enter the value you want for ‘location’ and ‘time’ just before the proof stage. 

You will then need to either click ‘change to free text entry’, where you will be taken to a page to allow you to enter the text, or you can click ‘allow blank data’, which will keep the area blank on the letter where the merge tag is.
