Hello! I happen to have a few energy meters that measure the full rooms consumption along with a few key devices, simply because it is not (yet) practical to measure every consumer or outlet. However, in the Energy dashboard I can only select individual consumers. I have not found anything yet, but is there maybe a way to add a meter for a room or larger circuit, and then nest some individual devices inside that meter, so the total consumption would be displayed correctly?

If you want to aggregate measurements between "consumers" and have them shown as one in the energy dashboard the best way to do that is probably to create a template sensor that adds the values and have that added to the dashboard.
As a general observation I would prioritise to be able to measure consumption for the entire "house" before measuring every outlet. The dashboard is designed to show the total consumption and any individual "outlet" as part of the total. The risidual consumption that is not covered by an individual measurement will then be calculated and show as Other/rest.

I am lucky to have a energy provider supplied smartmeter that integrates well into home assistant. The total consumption is not a problem and long dealt with.
I am also aware about how I can use template sensors, and I already use one to subtract my balcony solar system from one rooms counter which fortunately works well.
It would be just much nicer if I could just add a device to the energy dashboard, and tell the dashboard that this device is a child of another consumer that I have in the dashboard.
The way it is solved right now I either add the meter for the room, or for the individual devices. If I add both the Other/rest value will be wrong. Unless I add another template sensor that calculates the Rest and I add this, but this is not a nice user experience at all and prone to errors down the road as I add more meters and the system becomes even more complicated ...

Ahh, that sounds like one heck of a set-up, and it looks like that would need to be implemented natively in HA. Maybe implemented using a sensor group as the aggregation level.

You can use something like a sankey chart to create more groups for consumption measurements without having to do math or templates for it

oh yes I do have a dedicated page for my energy monitoring including a sankey chart. I do see which part of which room consumes how much power at a given time. However the energy dashboard is such a nice and well thought out tool, I really prefer using that to check how much energy which part of my hows has already consumed in a given time span. That's where the energy dashboard really shines.
