Unfortunately this is not something that can be addresses in Page List Teasers -- there is no way for this addon to know what the actual content of the various blocks on the page are. It just takes what's on the page and displays it somewhere else -- at no point does it have any opportunity to change the way that the blocks on that page work.

It's something that will need to be addressed in Pro Blog itself (although note that there are other problems that might occur if this change is made in Pro Blog -- for example, if you have one of these social sharing blocks in the "page defaults" so that it appears on new blog posts by default, it will need to link to the page it's being displayed on and not the original page (which is the opposite of what you're asking here) because otherwise the social sharing links would all point to the page defaults page instead of the blog post page.

It's a tricky issue and I'm not sure there's a good solution for it (but if there's any solution for it, it will have to be solved in the Pro Blog, not in this addon).

Sorry, wish I had a better answer for you :(
