remove the group $ portion from the subject id column in the datahub export

[david-roper]

Current Implementation and Limitations

currently the datahub export feature displays the subject ID column as so:

root$customID

Associated Application Components

Client

Proposed Solution

I would be better if the subjectID was done like this instead:

customID

with maybe adding the group as a separate column if needed.

Estimated Difficulty

Low
