Is it possible to have more than 10 read-only users?

Is it possible to have more than 10 read-only users?

Hi

I need to log time for staff, but these staff have no need to access the projects system. I can't just type names into the time logs, they have to be users it seems. However, I don't want to pay for extra users when they will never access the system.

I have seen there are 10 read-only users with the Enterprise plan, but we will need about 20 read-only users. Is it possible to get more?

If not, is there a way to log time for staff without having to create and pay for user accounts for them? It seems ridiculous to have to pay $9 per user when the only thing we need to do is log their time in timesheets.

Thanks
