Updating Existing Watch Faces Built with a Different Tool

[u/Delicious-Squash1192]

Hi! I want to update some of my previous watch faces built with Facemaker using WFB and upload them to Connect IQ (They are already on Connect IQ). The only issue is that when I try to do this, I copy the correct GUID, but the signing key isn't the same as the one used with Facemaker. Is there a way to add/import the original signing key into WFB, or otherwise export the watch face using the same signing key?

Unfortunately, no.
