This is not possible. Input to all GROMACS tools must be in one file, with rare exceptions for algorithms that do the same thing on several files. Either you need a filesystem capable of dealing with the large file, or follow the advice here http://www.gromacs.org/Documentation/How-tos/Reducing_Trajectory_Storage_Volume
