This would be useful when sending appeal letters with a correspondence template, such as a letter. If we could enter an eTapestry Merge Value that would create a "gift string" that's customized for that donor, our letters would truly take on a more relevant and personal ask, resulting in higher gifts  - this is proven by research. What if the merge value was based on the "last gifted amount"  and we could use a formula that increased that amount by a certain denomination, such as $25 more, and also $50 more. This would create a personalized gift string. These strings have been shown over and over to help donors increase their gifts, especially in annual appeals.
