You can export Startwork to any recipient. Just enter the email address(es) into the "Email link to:" entry point. You can add multiple email addresses by separating them with a comma (ex: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org).
When exporting to Payroll, TiM will pre-populate email address(es) in the "Email link to:" field based on the Paymaster Email Addresses entered in Production Info (the email addresses in the image below are just an example). These pre-populated email addresses are just a default and can be edited!
Currently in TIM, there is no way to pre-set email addresses for any other Export Tag.
