Initial condition on boundary?

Hello,

I am trying to implement a transport of diluted species model. The initial concentrations I want to implement are space-dependent. In particular, I want to supply an initial concentration at a boundary that is different from the concentration in the rest of the model space. However, COMSOL only allows selection of domains for the setting of initial conditions. How can I put in initial values that are space-dependent, and in my particular case, initial conditions in DOFs that are on certain boundaries?

Thanks!
