Yeah. You can achieve your requirement with my suggestion.
Please go through SCN "Rules of Engagement". When any reply helps you, you can mark that answer as "Helpful Answer". Likewise, you can mark up to 16 replies (if they are really helpful). You might have observed in other people's posts and How they are closing their questions.
You can close your post by choosing "Correct Answer"(if you have really got right answer). This is called good behavior in SCN.
