Change the colour pallet used for the dark theme

Is it possible to change the dark colours used for the dark theme? I am collaborating with another company using functionality developed in AppSheet to support a dashboard the company has built. Unfortunately they use dark blue hex #192132 and hex #021F38 as their dark-view pallet. Hence the question / request.

I can see it being useful as a feature going forward to help further customise the look and feel of applications being developed in AppSheet. Don’t stop at the dark theme, possible to change the light theme too.
