An option to sign the push by default

Hello folks,

during the configuration of git, client side, to sign all commit I used:

git config --global commit.gpgsign "1"

Since at push time I use:

git push --signed

I'm wondering if there is a git config option which put something in the config file and avoid to type --signed.

If there isn't this feature, I'd like to know if it is a reasonable feature request.

Thanks in advance.
