Automate Several Attendees visibility in single user

Summary:

We can add attendees one by one in the expense item creation apart from user as an attendee under single user login. But we would like to automate several attendees' addition in one user login instead of manually adding it.

For example:

The user has a team (8 members including user), and they are going to create an expense item for travel expenses, including meals and adding the attendees manually. Here instead of adding the attendees is there any way to automate these employees under user login while creating expense items?
