SFDC multi-select field-Change data value

[Amber_Hobson]

Hey all! We are looking at cleaning up a few fields and by doing this, I want to move them into a field that syncs from our SFDC database that is a multi-select picklist. I want to make it so that it adds the new value to any existing values that were already in that field. So, if someone has value 1 & value 2 already selected in SFDC, and my campaign is to change the data value to also add value 3, how do I get it to add that to the field and not overwrite whatever is in that field to only show the new value?

If you want to concatenate you can run Change Data Value

{{lead.Field 1}} Value 3

{{lead.Field 1}} {{lead.Field 2}}

Does that work if the field in SFDC is a multi-select field? Or do I need to do a ; in between the token and the new value?

How would this work if you're changing the value for multiple contacts who have different options chosen in this specific multi-select field?  Some may have 2 options chosen, some may have 4, etc.
