[Question] How to chain two protocol in sing-box config ?

[Mohsen7s]

Lets say I bought 2 different configs which ss-1 is blocked in country and cant connect to but the ss-2 is Ok.
I need to have my dedicated IP at ss-1. So I want to firstly connect to ss-2 and then connect to ss-1 through ss-2. Keep in mind I dont have access to server and can only play with local sing-box config.

    {
      "type": "shadowsocks",
      "tag": "ss-1",
      "server": "2.2.2.2",
      "server_port": 57456,
      "method": "chacha20-ietf-poly1305",
      "password": "123"
    },

    {
      "type": "shadowsocks",
      "tag": "ss-2",
      "server": "1.1.1.1",
      "server_port": 57456,
      "method": "chacha20-ietf-poly1305",
      "password": "435"
    }

I want to connect to ss-1 through ss-2. I mean first ss-2 must be established and if success then ss-1 should use ss-2 connection to establish.

Is there any option to do so ?
