Add a custom tunnel feature that allows selecting multiple countries globally. For example, Tunnel 1 could include the United States, India, Canada, and more (users can add 30-40 countries).
Add a custom route feature with DPN mode, allowing users to configure multiple tunnels in a specific sequence.
For instance:
Route 1 - Tunnel 1, Tunnel 3, Tunnel 2, Tunnel 6.
If Tunnel 1 has no nodes, switch to Tunnel 3.
If Tunnel 3 has no nodes, switch to Tunnel 2.
If Tunnel 2 has no nodes, switch to Tunnel 6.
