Comment 2 for bug 357177

Michael,

Yes, on the presence of the signing-key for the default ppa (the one named 'ppa') we can certainly configure the subsequent ones to use it immediately. Although, the current ETA for a signing-key should not be longer than 10 minutes, IFACT.

Regarding existing named-PPAs with dedicated signing keys, the owner may request (by filing a question on soyuz product) the existing key to be re-used in his other PPAs. I don't think it's a good idea to spend time designing a UI for since sharing signing-key will be compulsory after this bug is fixed.
