Is it possible to append data to a field via a Marketo form?
I've found documentation on how to append data to a field by using the Change Data Value flow along with tokens. But is it also possible to append data when it's submitted through a form?
We have a text field where people can write down their inquiry details. It would be helpful to append this data each time the lead/contact returns to our website to fill out a form with a new inquiry. At the moment, the newest value just overwrites the existing value.
Can this be done on the form side or only through smart campaigns with the Change Data Value flow step?
