Problem with Russian translation in title (wc-comment-title)

Hello, In English  there are two forms for count comments: singular - 'Comment', plural form - 'Comments' and the problem is in Russian language there are more than 2 forms like  1 'Комментарий' - for 1 comment, 2,3,4 'Комментария' for 2,3,4 comments, 5,6,7,8... 'Комментариев' for 5 comments and etc.  and it looks stange with only two possible forms I can translate from admin panel. 

Can I fix it something like this: Quantity of comments: (number of comments) on ..etc. On Russion: Количество комментариев: (number of comments) on ..etc
