In console when manually creating a new CSR, you have select the Tile Set.

The AddAdminUser endpoint offers all the necessary details except Tile Set.
https://dev.q2api.com/v2/AddAdminUser
{
"LoginName": "CSRUser",
"FirstName": "Test",
"LastName": "User",
"Email": "noreply@q2.com",
"AdminGroupID": 1,
"ABA": "07777777",
"Phone": "512-123-4567 x1234"
}

Has anyone come up with a way to programatically add the Tile Set to the user? Or will the Group membership grant the Tiles?
