Hi experts,

When we go from My Client Groups → Succession Plans, by selecting a succession plan we can see the section "Candidates".
As you can see from the screenshots, there are several options in the Sort By menu, but there's no option to sort by last name.

Is it possible to customize this menu by adding the last name option? Is there a configuration page for this menu or maybe we can use Visual Builder?
