Describe the bug
I am interested in the python code generator.
I would like to edit the code snippet manually myself and totally disable any interference by the auto code generator (that keeps overriding what I have manually copy-pasted in). If there is a way that this can be done, then I would be very keen to know. Thanks

To Reproduce
Body has this raw json:

{
    "outputs": [
        {
            "value": 0,
            "script_pubkey": "6a0548656c6c6f"
        },
        {
            "value": 100,
            "script_pubkey": "76a914fc746b833ca84043e0c7d606de8ecc4b7f3b7cd688ac"
        }
    ],
    "password": "test",
    "utxo_preselection": true
}

Expected code snippet and corresponding request
I want it to look something like this:

import requests

url = "http://127.0.0.1:9999/v1/stn/dapp/wallets/my_wallet.sqlite/1/txs/create_and_broadcast"

payload = { "outputs": [{"value": 0,
                         "script_pubkey": "6a0548656c6c6f"},
                        {"value": 100,
                         "script_pubkey": "76a914fc746b833ca84043e0c7d606de8ecc4b7f3b7cd688ac"}],
            "password": "test",
            "utxo_preselection": True}

headers = {'Content-Type': 'application/json'}

response = requests.request("POST", url, headers=headers, json=payload)

print(response.text.encode('utf8'))

Screenshots
Instead, it looks like this:

import requests

url = "http://127.0.0.1:9999/v1/stn/dapp/wallets/my_wallet.sqlite/1/txs/create_and_broadcast"

payload = "{\n    \"outputs\": [\n        {\n            \"value\": 0,\n            \"script_pubkey\": \"6a0548656c6c6f\"\n        },\n        {\n            \"value\": 100,\n            \"script_pubkey\": \"76a914fc746b833ca84043e0c7d606de8ecc4b7f3b7cd688ac\"\n        }\n    ],\n    \"password\": \"test\",\n    \"utxo_preselection\": true\n}"
headers = {
'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data = payload)

print(response.text.encode('utf8'))

Start with the Python code generator and reproduce the issue using the raw JSON body shown in the report. Verify how manually edited snippets are saved and whether regeneration overwrites them; done means the requested Python formatting is preserved and the generator no longer replaces manual edits.
