I'm not aware of any quick fix to that effect. Maybe others know of a built in preset that will do with their own software but I do not.

If I were to try that I would do it in Adobe After Effects. Trapcode Shine is good plugin that does the light gleam but you can do it without it. A bit of masking and compisitign and it should fall out ok.
