This can be done by editing the dia.yml file. Inside of it there will be a presentation section. You can edit the 'page' value.
In the example below we are specifying the path of 'idigi_dia'. So the end request will look like this (IP address will vary of course)
- name: web0
after making the change you will need to upload the new dia.yml configuration to the Digi.
