How to Change Quote# Letters

Currently when we create a new quote the letters in the Quote# are “QU” I would like to change those is this possible? I know I can go into the DB and into the table and change the existing ones, but I would like the application instead of already knowing to use “QU” to use the letters I would like to input, that way it generates the proper Quote # each time.

Take a look at the invoice groups (under settings) and edit the "quote default ".
