System Email Signature or Footer of Each Email

It would be great to have a branding section where we can customise the company logo, company name, and contact details for Email Signature. This would make emails appear as though they are coming directly from our company, helping our clients easily recognise our branding - at the moment there is no email signature although it goes with our custom domain and logo- but having signature option would make more difference- the simple option is to allow copy and paste html signature like gmail and outlook.
