Can I set the subject line to wrap around in folder pane? If so, how?

I have my view set to Vertical - Folder pane and Preview pane side-by-side. I like to be able to display more of the subject in folder pane without enlarging the folder pane's width of reducing the width of the preview pane. Is it possible to make the columns in folder pane to wrap the information into two/three lines? If so, how do I do it? I have looked at each and every option but haven't been able to find any setting to do this. I have, also, checked the add-ons but haven't found anything.
