As stated, Sequence Liner from Spherico does this, but it’s only for FCP 7 and earlier. Sounds like you are using FCPX because you mentioned Gap Ciips.
Avid has this feature and it’s called Autosequence.
This is the FCP 7 forum. You might get a better solution in the FCPX Techniques Forum. If you are looking to have the same six people have an endless, heated, circular discussion, that has nothing to do with your question, try posting in the FCP X or Not (The Debate) Forum.
