Use shortened title, but not change title

Is there a way to replace the title text in the menu without changing my title of my page?

Here is the page: https://www.ecsnj.org/support-ecs/ways-to-give/

In the blue menu on the left there is a link for a Campaign for Elysian Business Donors. I would like to shorten it to CFE Business Donors. Is there a way to do that without affecting my title as it appears on the page. I just want it to change in the blue menu
