Hi. When we place orders now on US stock there is the option to enable extended hours and in the portfolio view the extended hours orders have a little icon next to them. It would be useful to be able to convert existing orders over to extended hours orders rather than have to go through the entire portfolio to cancel and replace every order.
Thank you for sharing your feedback, @WakeMeUp 
While such a feature is not present currently, I understand how it may be useful, and I’ll pass your feedback on to the team. Let us know if you have any other ideas in the meantime.
