Trying to add a span into a <a> tag in a dynamic wordpress nav

I am trying to add a span tag inside a tags on the sub navigation on the second level on the page url below.

I have only been able to find solutions to do this to the main navigation and children and grandchildren navig开发者_StackOverflowation.

How would this be possible with php of jquery?
