Classic Outlook Integration Default Team Sync

I'm a system admin who is fairly new to Sage. Our company uses the Outlook integration plugin versus the exchange integration for security/server reasons. When users sync appointments or tasks from Outlook to Sage, it automatically defaults the "team" setting for that item to the user's team (in the below photo the user's team is "Default", but we want it to default to "--None--"). The only way I've found to "fix" that is to change the user's team setting to "unassigned" in the system admin settings. Howevever, we want our users to have a default team for purposes outside of the calendar, specifically our sales team.

The main issue we are having is that sales reps and managers who create tasks/to-do lists/appointments in outlook for personal use and time management, don't want all of those items to automatically show up in the Team CRM Calendar for the team they are assigned when Outlook syncs with Sage. They'd like it to default to an unassigned team, and then pick and choose which items to add to their Team CRM calendar.

Any suggestions on how to make the team default to "--None--" only for the calendar when they sync?
