Apply a signature to all prior posts?

Just curious if this can be done. I only just started using a signature. Is there any way to apply it to all my previous posts without editing them? Some kind of option I'm not finding?

It should do it automatically. Your signature is independent to your post afaik.

Each post has an individual setting for whether to show your signature or not. Unfortunately this setting is off for the random older posts I checked (I think it defaults to off for new posts when your sig is empty), and I don't know of any way to turn it on except by individually editing each post and checking the checkbox for it one post at a time.

Thank you for your responses. I just hit 500 posts soooo I think I will just live with not having a signature on all of them, rather than editing
