Set Clip Times in AllAnimations.FBX

When I import the AllAnimations file all the animations are visible but then need to be seperated manually using clipping times. See:

Animation@AllTogether_Imported.png - What is looks like right after I import the FBX into Unity

Animation@AllTogether_ClipsAdded.png - How it looks after I manually add a few clips

Do you know if there is a way to add these clipping times to the FBX file with MAYA? Right now I am just guessing approximate times by scrolling though the animations. If it cant be added before I'll just need the times when the clip changes so I can add them exactly right.
