More flexibility for personalize token settings for follow up emails

Hi team スマイリー ハッピー

I recently recieved some feedback from customers about the personalization token in followup emails.
It is currently not possibel to show only updated properties which are changed by the form submisions . (e.g. If a contact submitted the choice A previously and did not submit any value on the follwing form submissions, it will still show choice A if the property is not updated since the personalization token is there) 

What I could come up with as a workaround is create each workflows/emails with specific personalization tokens to suit their needs.
But it will great if there is any other settings such as only shows the prooerties which are updated by forms.

This is a just idea. But it is something beneficial for some customers!
Thank you スマイリー ハッピー
