I have created a custom Footprint representing the customer's segment (not related to Audience Manager segments) and its currently working fine set up as a FootprintRadio control, allowing the Editor to select a segment from a predefined list of values and preview content variations on the page based on this segment.

A site visitor can be in multiple segments, so I was wondering how/if I can get this working in XPM Preview? Ideally there would be a FootprintCheckbox control, but this doesn't seem to be an option. I was thinking of implementing it myself (based on docs) but am not sure if I can pass a multivalue claim to the ADF Claimstore via the Footprint cookie?
