Linking audio from aboom mike to video clips

This is probably easy, so I apologize if this is simple and I am just missing it. Here is what I need to do: I want to take the audio file from a boom mic, the video file from the camera, and after syncing the two files, use them as one file. Currently I sync them up in a sequence using the clapboard in every take, export the file with the synced audio, then re-import it. There has to be an easier way, right?
