Lens Flare as transition BCC5 FxPlug FCP

I have done this with an Avid but cant get the same effect to work with FCP. With Avid I make a 10 frame cut on video track 2 between the clips and drop the lens flare in and it works perfect as a transition. Any suggestions on how to use the Lens Flare as a transition with similar result? I tried overlapping the clip at the tail and adding the effect but that didnt look right. Also tried it in a cross dissolve but dont like the look with the dissolve. The beauty of the Avid technique is the effect has a alpha channel look to it so you can blow out the flare in between the clips for the transition.
