Completely brand/change "wordpress" text globally in multisite

I want to totally change the text “wordpress” in multisite with my site name. I have used the ultimate branding text change module globally but I still see the wordpress text in some places within the multisite.

For example, when I hover across the tab of a multisite dashbord page on a browser, it displays the following crumb: Dashboard > site name – WordPress. I want to totally brand the wordpress text with my custom text however it takes, even if it requires editing php files as I am a programmer.

How do I accomplish this as it doesn’t seem to be possible with the ultimate branding plugin. Thank You
