verbose sftp per user ?

[jul]

Hello

i'm using chroot sftp with the following command:
#Subsystem       sftp    internal-sftp -l VERBOSE -f AUTH
Subsystem       sftp    internal-sftp -l INFO -f AUTH

from http://marc.info/?l=openssh-unix-dev&m=120969706821519&w=2

but is there any way to restrict verbose/info logging to some users ? or
trap to /dev/null log of some others ?

for example:
Match user user1
        Logging VERBOSE


thanks a lot
Best regards

        Julien
