I'd like an account field called "acquisition channel" to be changed according to the acquisition channel of the first contact in the account.
-A user clicks a PPC ad and creates an account
-Our app creates account&contact
-the data is synced to marketo
-A triggered Marketo campaign changes a Contact field called "Acquisition Channel" to "Paid". I'd like the same to be changed in the account level, but then if more contacts are added to the account I don't want this field to be changed anymore, in case they reached us thru other channels.
Couldn't find a way to achieve it using SF Workflows
