Yes, I think I understand.

What you want to do is go to the level options, and set the next level feild on all your levels in a chain. SO, MyLevel1.J2L would have the next level setting of MyLevel2.J2L, and MyLevel2.J2L would have the next level setting of MyLevel3.J2L, and so on. Then, check the check box that says somthing like "Hide this level in the homecooked levels" on all the levels but MyLevel1.J2L. That should do it.
