Blogger RTL/LTR Title Adjustment

We have a Blogger blog and we are publishing posts in both a RTL language and a LTR language. We are facing an issue with the post title's alignment. It is either RTL for all the posts or LTR depending on the blog overall language(Locale) defined. We are aware that this alignment adjustment could be achieved by adding some code similar to this post: [login to view URL] But we need a button that appears on the post editor ([login to view URL]). The button will automatically (once clicked) will make the post title aligned to left (LTR) once the post is published. If not clicked, the post title will remain RTL by default as this is the blog locale.
