DSCP support

Hello, a new user here.
just received my purple box recently and have been quite happy since that.
However migrating from Cisco897 router, there are still some things missing.
Proper QoS implementation is one of them.

Tried to search for that here but to my greatest surprise - that was not mentioned before so here is my question/suggestion:

Is it possible to make Firewalla pay attention to DSCP marks?
I can mark my traffic the way how I want it, right on a PC so if I could make Firewalla honor that marking - that would be great.
I want to be able to prioritise traffic not by IP address or ports but by applications.
For example I want to prioritise traffic from/to web browser but Steam client uses the same IP, the same port (443) so Firewalla can't really distinguish between them (unless it looks at destination IP but that is not super reliable IMO).
There are programs that can mark traffic per app but Firewalla just does not care at the moment.

Any ideas? Should I raise a feature request may be?

Thank you.
