Data Link Access Control Based on Attribute and Groups

Is it possible to control if a data link will load data based on an attribute criteria and the logged in user group membership?

For example:

• If a feature attribute [colour] = red, and logged in user belongs to the group “Red Group”, show the associated related record via data link.  
• If a feature attribute [colour] = red, and logged in user belongs to the group “Blue Group”, show “No related records”.  

There's the “Get Portal User” activity that can output the users groups, but I'm not sure how to apply this activity with a data link server workflow to perform logic on whether the user should be able to see related records.
