Show new item in menu >>Purchase Receipt Hub

Hi,
Is it possible to highlight or to add a number in brackets to the Receipt Hub line in the top menu when there is a new item in my receipt hub? Something like Receipt Hub (1) for one new document.

I am not so often on the dashboard and miss very often when a new receipt is available. For me, it would be very helpful. I am not a programmer/developer but hope it is quite easy to implement that.
Thanks in advance.
