Removing personal Email Signature when using Organization Wide Email Address

Hi All,

I am using Apex SingleEmailMessage to send out an email message, and utilizing the setOrgWideEmailAddressIdto make sure this e-mail appears coming from a company e-mail and not from a specific user.
If users have a personal signature set up, the signature gets appended to the bottom of the e-mail message.

Does anyone know of a way to force the message to not include the personal signature?

Thanks!
