Is applying customized initial solution supported in CLP

I plan to use the CLP to solve some large-scale LPs. Especially, I can acquire some initial solution with good quality and want to accelerate the process using this information. Is there a way to feed a basic feasible solution to the solver and start to solve the problem from there.
Further, as there is a presolve function in CyClpSimplex module, how is the presolved solution is utilized by the package? Thanks.
