Add item ID as a class to all Joomla Yootheme Pro Menu items

I am looking to have the the Joomla Yootheme Pro menu code modified so that the ItemId # is added as a class to the html. So for example, in the Youtheme Navbar menu items, each should appear as:

<ul class="uk-nav uk-navbar-dropdown-nav uk-nav-parent-icon" uk-nav="">
<li class="uk-parent"><a class=ITEMID-#"> </a>
.
.
.
<ul class="uk-nav-sub" hidden="">
<li><a class="ITEMID-#" href="/URL"> TITLE</a></li>
</ul>

Requirements:

- Must work on both the main uk-navbar-nav AND mobile menu module-menu-mobile
- Must add menu item to ALL Joomla menu types including external URL and menu headings
- Work with the Yootheme pro package provided in this brief (or use your own):

- Modify code and demonstrate to me it works on your server
- Provide me the code changes in a written document showing what files were changed and what changes were made.
