It would be possible, but why exactly would you want that? I am asking because from what I noticed, you are not the only board with similar topic, where people share their good posts to local merit sources. Imho, even those posts should count towards your total number, there's nothing weong with that.
I'm curious about the difference between the statistics with and without that thread. Because some users
only send merits there and never distribute them in the rest of the forum. In addition, there are a lot of people who share their random messages and get merits. I'm not against these kind of threads, ideally you post your quality posts and get merits for those posts. But people send merits to those lists without even checking the content. Even foreigners who saw that this was an easy way to earn merit started to write on the thread and get rewarded.
