Caching all subkey passwords at once?

[adrelanos]

Hi,

I find it a bit inconvenient, that I have to enter my password multiple
times (once for decrypting, once for signing). Can gpg-agent be
configured to ask for all passwords at once and cache all of them?

If not, is there a workaround? I could imagine that someone may have
written a script which lets one enter the password once and tell
gpg-agent about it for all subkeys.

Cheers,
