All things can be done... But they don't or not inclined to do it.

All these days SCR was opposing extension since it will loose SF status in SBC-MYS since it was Single & Diesel and now even after becoming FEDL they are making it crawl in the extended portion atleast they could have cut slack while reaching SBC instead just added to it. Possibly just a thing to see it keep running on tracks to cut idle time.
