You can indicate which title is the primary comp suggestion from the list. The starred comp is available to be viewed by all CataList account users and will be prioritized into the Comp 1 ISBN and Comp 1 title columns for any users who have selected those columns in their grid view and export settings.
Any user in your account for your own titles can star a comp title. The star is applied at the title level (not a the rep-per-title level) - if you have multiple reps you may want to internally manage which staff should be setting the starred comps for your titles.
