apt.conf.d: Multiple declarations of one value?

[mad <mad@sharktooth.de>]

Hi!

Does anyone know if it is possible to specify a configuration option in
apt.conf.d multiple times and all values will be used?

Example:

$ cat 50unattended-upgrades
[...]
Unattended-Upgrade::Origins-Pattern {
        "origin=Debian,archive=${distro_codename},label=Debian-Security";
};
[...]

$ cat 90local
[...]
Unattended-Upgrade::Origins-Pattern {
        "origin=Other,label=Other-Security";
};
[...]

Or will then only the last definition be used?

TIA
