Admonition with custom title to latex

[pcsi3physiquestan]

Hello!
I'd like to customize the admonition environment in latex. It's possible with classic directive {attention},{danger}... but if I use an admonition block with a custom title, the builder create a "sphinxnote" environment whatever the class is.
Is there a way to change this behavior : transform an admonition block with custom title to the correct environment (class attention => sphinxattention, class important => sphinximportant ...) ?
Thanks.
