Possible to control TV volume with the remote?

Is it possible to disable the box's volume control and set the remote to control the TV volume instead? If not, can we please add this as an option in a future update?

I can power on the TV and change sources using the Dreamlink remote but I cannot adjust volume.

If I want to use my Amazon Fire Stick, I pick up my Fire Stick remote, turn on my TV, change source, and adjust volume all from one remote.

But if I want to use my Dreamlink box, I'm forced to use two remotes for one device.
