Can I over ride the "Blocked (System Managed)" error that appears when you try to upload and assign at the same time? Just wondering why it's an option if we can't choose it.
If you are not in a CRM-enabled Marketo subscription, you can use the new Sales Person API (Marketo REST APIs: Sales Person Objects » Marketo Developers )
This is not possible via a list import in Marketo. You will have to either do it in your CRM or create a smart campaign that updates the records' owner. This can be time consuming if there are multiple owners in your list.
There were two different lead owner's in one column. So, I just separated the list like normal and ran the change owner step in the flow. Just thought there might have been another way since they have the owner field available in the drop down.
