Change boundary patch type within LES model

I'm trying to implement an LES model that solves 1D equations for the small-scale velocity within each cell. I use only one subgrid mesh to solve the subgrid equations on each cell sequentially. This is required to save on storage. For internal cells the boundary conditions are always cyclic, but I want to be able to change the patch type if the cell is on the boundary. So far, I can't figure out how. Any suggestions?
