Subscription Center - Uncheck options through Smart Campaigns

[cagarwal]

Occasionally, we remove people from specific newsletters to comply with business rules. In these cases, we need to remove the "check" from the "Checkboxes" field for associated newsletter on the subscription center form. Though it is easy to add values to a list using Smart Campaign Change Data Value, I was wondering how to remove them if necessary. Any ideas? 

For eg:

Current value is "Newsletter 1; Newsletter 2; Newsletter 3"

We would like to remove "Newsletter 2" through a Smart Campaign flow step.

The only way to manage multivalued (i.e. semicolon-delimited) String fields is via a webhook.

Thank you, Sanford. This makes sense.
