Updating "Team" field on a related module of a custom module

Hi!

We have a custom module that has a relationship with the "Calendar Lines" module. 

Our current operations work with all the calendar lines records on the GLOBAL Team to ensure the right access.

We have recently received complaints that some of the calendar lines are missing. I've mass-updated the associated contacts to the GLOBAL team and am looking for a way to mass-update the calendar lines.

As it is not a module like Contacts/Opportunities/ Tasks that is readily available from the Home bar, how can I perform this task?

The calendar lines module doesn't have to be visible/ accessible from the home bar, but the records have to be updated.

Any thoughts will be highly appreciated.

Best regards,

Gayathri G.
