Is it possible to add an Oculus signature file to an existing apk?

Is it possible to add an Oculus signature file to an existing apk on Windows? I have seen some threads talking about resigning an existing apk such as that below but they don’t seem to mention oculus signature files and they don’t seem to be talking about Windows.

you can add your signatures with aapt wich is in the build-tools folder of the android sdk before signing it.
aapt add -v youapk.apk assets/oculussig_*
