For this task:

1) Navigate to the relay type of interest inside the data manager.

2) Create a new relay object (ElmRelay) and name it "default".

3) Assign the relay type to this new relay.

4) Once the type is assigned, you can enter default settings inside your default relay.

From this point, each newly created relay of this type will be a copy of the default relay at the beginning, which can be further changed and adjusted.
