rewrite existing filename

[hxss]

requests.get(
    'http://localhost:8082/api/test/1',
    data = {'v': 'ads'},
    tabname = 'test',
    fmt = 'raw',
    filename = '/home/hxss/1.html',
)

Please add rewrite option for filename argument. Often it needs to test same request and quickly check for answers changes. Open new file every time is uncomfortable.
