How to cumulatively add to a picklist value already existing in field for the lead?

[Nancy_Rosentha5]

Does anyone know how to assign "Additional" values to a field for a lead that already has one value there for a multi-select picklist field? Change Data Value just seems to replace whatever was there before, while I would like to add another picklist value to whatever they had previously.

Change Data Value including a {{lead.token}} in the New Value box, with a semicolon in-between the current value(s) and the new one(s).

   Your Field ⇒ {{lead.Your Field}};Some New Value
