Limit emails shown in Assignee drop down menu

Is there a way to limit what names/email addresses are offered in the drop down menu when clicking on ‘Assignee?’

For example, working on a Project and screen sharing, and want to assign a Task to the individual you are sharing screen with, but don’t necessarily want them to see other names/emails that aren’t related to the project or Team they are on.

Is there a way to either limit the names and emails shown only to those associated with that specific project, or otherwise disable the drop down feature and only assign tasks by emailing individual directly?
