Hello Qualtrics Community,

I am currently working on building a survey where we aim to authenticate respondents based on a unique contact field. However, the challenge I'm facing is that each main contact may also have associated contacts, like dependents, that we need to account for in the survey.

Is it possible within the XMD to create a Contact hat has associated contacts? Essentially, I am looking for a way to link multiple contacts under a single unique id for authentication purposes.

Has anyone encountered a similar scenario or have any recommendations on how to achieve this in Qualtrics?
