Highlight Text in a PDF in endnote with different color then yellow

Hey I’m using windows 8 and when i’m reading a PDF file from Endnote I can only Highlight Text in Yellow.

II cannot mark different subjects or theams in a different one which make it harder and time consuming to identify the relevant material after reading several articals.

It will help a lot if that option will be avilabal for windows user as it is for mac useres .

Kind regards Michal
