We have the option to pin people to the top of a list so that every time this list is opened, your pinned people will appear at the top with a yellow highlight.
To pin people to the top of a list:
1. Open your list via People > Lists
2. Whilst viewing your list, use the tick boxes in the top right corner of a profile to select the person/people you want to pin
3. a 'with selected' menu will appear at the top - select 'pin to top'
TIP: Use this feature to highlight the people you are considering for the role or those who you ended up taking on for a job
