Using model boundaries, not domains, for heat source

Hello,
Is it possible to somehow use the model boundaries instead of the domains to define the heat source parameters?
The domain selects too many different features, with boundary in other nodes I can selecte specific parts of the model
Edit: I have created an explicit selection using 'Boundary' as the geometric entity level, but in the Heat Source node (Under Heat Transfer in Solids), there is still no option to select it.
Thanks in advance!

Try using heat flux in the same physics

Allow me to expand a little William's answer: a volumic heat source in a domain transforms into a heat flux when the heat source comes from a boundary. In a 3D problem, on a boundary the heat flux is W/m^2 whereas in the same problem a heat source that is for instance distributed in a domain is in W/m^3.
