Update Date?

Hello, this plugin is awesome but I was thinking if it can be created a plugin to change the post date to the updated date… like WP Date Remover does but instead of removing the date changing it to the updated date of the post.

Because I make a lot of changes in my posts to meet with the latest information but when I go to Google to see how my pages are indexed it shows the post creation date that is 2-3 years aged being that I updated all the information last week to meet the current facts… There are certain situations that it is better to use the same post instead of creating a new one for SEO… I was thinking if your plugin can help with this.

Thanks.
