I'm hoping to be able to create a custom field in Salesforce, and update that field using the Journey Builder 'Object Activity'.
Ideally, at the end of a Journey, the Object Activity would pass a text string, such as "MM/dd/yyyy HH:mm:ss - Completed JourneyName", and the field in Salesforce would record multiple updates, creating a log of Journey activity.
Is this possible using MC Connect?
From what I can see, it looks like Update Options are limited to "Overwrite" and "Overwrite (only when null)". Is there a way to just add a value to a Text Area field without overwriting it?
