Where can I change the include transaction {includetransaction} checkbox preference for sending emails? The type is set to default, I want to change the preset to "PDF"

AI generated answer (using internal Slack threads):

The preference for the Include Transaction Type default for sending emails can be changed in several places: 1. User Preferences: Go to the Preferences tab for a User, under Transactions -> Printing -> Transaction Email Attachment Format. Here you can set the default format for transaction email attachments. 2. Customer Record: There is also a per customer preference on the customer record. You can create a Workflow on the Customer record to set the Field Value to PDF in the Email Preference field. This will ensure that when invoices are manually sent to customers, the format will always be PDF. 3. Role Preferences: There is a Preference under the role -- Transaction Email Attachment Format. You can set this to PDF to enforce this setting for all users assigned to that role. Please note that the Customer record preference will prevail over the User Preferences. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
