Adding email signature to automated emails

When creating an email automation (if status changes from this to this, send email via outlook to emails) you can currently only copy and paste the text of your email signature, however it would be good for the HTML email signature to be pulled through (including logo, bold formatting etc) rather than just plain text and sent with the body of the email, otherwise all the texts blends into one. The email signature can be added to the settings in so why can’t this be pulled through to the automated emails if your outlook account is synced/connected already?
