Sort By Date

Is it possible to have the date column in the orders section (admin backend) pick up the last modified date/time instead of the creation date/time of the order?

We regularly edit orders for customers before the order is placed and it would be useful to have the order move to the top of the list when modified, as sometimes we could change a month old order before the customer wants to pay for it

I am afraid, it is not possible out of the box
