How to add more custom sampler presets?

[Hamsterun]

I would like to test some newer sampler, but I don't get how to add multiple samplers presets to the JSON.
I couldn't find the answer in the doc either.

The JSON looks normally like this:

{
    "My Custom Sampler - DPM++ 3M": {
        "sampler": "dpmpp_3m_sde",
        "scheduler": "exponential",
        "steps": 20,
        "minimum_steps": 5,
        "cfg": 7.0
    }
}

Where do I put more presets? I tried single files.
Tried like this:

{
    "My Custom Sampler - DPM++ 3M": {
        "sampler": "dpmpp_3m_sde",
        "scheduler": "exponential",
        "steps": 20,
        "minimum_steps": 5,
        "cfg": 7.0
    }
}
{
    "My Custom Sampler - DPM++ 3M": {
        "sampler": "dpmpp_3m_sde",
        "scheduler": "exponential",
        "steps": 20,
        "minimum_steps": 5,
        "cfg": 7.0
    }
}

And tried like this:

{
    "My Custom Sampler - DPM++ 3M": {
        "sampler": "dpmpp_3m_sde",
        "scheduler": "exponential",
        "steps": 20,
        "minimum_steps": 5,
        "cfg": 7.0
    }
   "My Custom Sampler - DPM++ 3M": {
        "sampler": "dpmpp_3m_sde",
        "scheduler": "exponential",
        "steps": 20,
        "minimum_steps": 5,
        "cfg": 7.0
    }
}

But no presets were shown in Krita. I restarted Krita every time.
How can I add more presets?

You need to add comma between the custom sampler blocks, next to the curly bracket separator:

{
"My Custom Sampler - DPM++ 3M": {
"sampler": "dpmpp_3m_sde",
"scheduler": "exponential",
"steps": 20,
"minimum_steps": 5,
"cfg": 7.0
},
"My Custom Sampler - DPM++ 3M": {
"sampler": "dpmpp_3m_sde",
"scheduler": "exponential",
"steps": 20,
"minimum_steps": 5,
"cfg": 7.0
}
}

and of course, name them differently.

Otherwise, your 2nd try was correct

I see, thank you. Didn't think about a comma. Yeah, I had different names.
