Dynamically change email signatures when switching to shared emails on E&A under CRM

In emails and activities CRM, there is an option to share email access, so I can easily switch and reply emails from mine to my teammate’s email address. The only issue is, the email signature doesn’t dynamically change when I switch emails. So I maybe replying as my teammate but my signature there stays the same- my signature.

Our team uses an html version of email signature so it’s not really easy and efficient to change it manually everytime I need to reply using another email address.

This is highly necessary especially to our Sales process. I hope this can be given consideration.
