Multiple email signatures per multiple email accounts

Is your feature request related to a problem? Please describe.
When a user has more than one emails account, it is difficult to use both emails hence only one email would be pre-appended with email signature.

Describe the solution you'd like
CRM could allow email signature to be added when a new email account is set, this way when a user has multiple email accounts everytime they send an email from one of their email accounts the CRM will append the related email signature for the given email account used to send email. this could be applied to both personal and group email accounts.

Describe alternatives you've considered
Add email signature to email account set up page.
