Creating file geodatabases with the same feature datasets multiple times

[LeeGray]

I'm looking for an answer to help me in creating file geodatabases with the same feature datasets many times without the need of doing it individually one by one, which is taking up too much time. Is there a script or tip or trick that can solve this???
