What is the IR sensor on the actual box like?

My duo you can use the remote even when the box is facing the other way i.e. the back.

Can you do that on the ultimo with one of those universal remotes or harmony remotes?

It is important for me as my box is situated at quite an obscure angle from where i sit and i really appreciate the duo ability to change channel even when no direct line of sight is there.

Please ultimo owners with harmony or universal remotes let me know if its possible

Thanks
