pdm export with the --group option

[renaudjester]

Problem

I want to create a requirement file using the pdm export command for a specific --group. Though, I cannot seem to make it work except if I do some workaround.

Here is a pyproject.toml that can be used:

[project]
name = "test_pdm"
version = "0.1.0"
description = "Default template for PDM package"
authors = [
    {name = "renaudjester", email = "hello"},
]
dependencies = [
    "sentry-sdk>=1.44.1",
]
requires-python = "==3.9.*"
readme = "README.md"
license = {text = "MIT"}

[project.optional-dependencies]
group1 = [
    "pandas>=2.2.1",
]
group2 = [
    "aiohttp>=3.9.3",
]
[tool.pdm]
distribution = false

[tool.pdm.dev-dependencies]
dev = [
    "black>=24.3.0",
]

To be able to get only the "group1" I am doing:
pdm export --group group1 --no-default --prod -o requirements.txt

What I expect

Something more concise like:
pdm export --group group1 -o requirements.txt
as for me the --no-default --prod is not very natural and well documented. It seems quite confusing to use those two options at the same time.
I think that poetry has --only and --with options, that could be a great addition.
Maybe I am missing something and if it's the case I'd be happy to get a proper way to do this!
