Name the feature! [on hold]

So I am currently designing a "check-in" feature for sport team managers on my platform. The managers have a list of the people who've signed up for their team and come start date & time they can check their members in to see who is attending. It's like when you were in 1st grade and the teacher called your name to see if you were attending the class, just for adults.

Now, the problem is that the company does not like the name "check in" for the feature because there are a two other companies who have called this same feature "check in". So they are looking for an alternative name to the feature.

What would be the most appropriate name for the feature based on usability? A brain fart have hit me, and I cannot come up with an intuitive name. Help please!

The name will appear on a menu for the managers to select and on the actual feature.
