Can I save a template of a mail I already sent?

Can I save a template of a mail I already sent?

Hello,

I worked and reworked a standard ZOHO template to fit the colours and design style of our company. Currently, I copy that email campaign (that was sent) so I can reuse the template for the new mail. Is there a way to save that email that I sent before as a template? Or do I need to start from scratch to create my own custom template?

Thanks
