Bring group attributes into Data Exchange to use in mappings?

Hi,

We are wondering if it is possible to bring fields from group attributes into Data Exchange, and populate values for those fields based on the value loaded for the corresponding key field. We are watching the Dec 2023 webinar on group attributes where fields are populated in the transaction matching account itself. But we want to be able to map to different reconciliations based on values within the group attribute.

The other option would be to use member mappings, but am curious to see if there is a better approach in Data Exchange where the mappings for different integrations could essentially be updated/maintained in one central location.
