Hi Emily, I've been sick and been slow to catch up on questions. One way to handle a custom sync rule without a SFDC workflow rule would be to set the value of the custom field using Marketo. This option will work as long as you don't have a large volume of records syncing daily, say less than 10,000. The requirement would be the custom field will need to be backwards from the recommendation noted in my article. Let's call it Don't Sync with Marketo. Use a batch smart campaign to do the following: Set the custom field used in the sync filter to True, use the sync with saleforce flow step to push the update to SFDC, wait 1 hour and delete the record in Marketo only. This goes completely against my article. Thanks!
