actually, popup plugin has a clone feature – you have it in the settings panel above all the options in the row delete popup, turn on popup and clone buttons
But insert it after each post you need manually, it will not take a lot of time. just clone and insert the shortcode.
Hello davincisbloglog again.
I gave the issue to our developers, because we definitely haven’t such a feature. They will tell if you can do it somehow, insert CSS code or something like this, or it should be an update. I will inform you as soon as they will reply.
