Are we able to control scale of pattern fill?

[Ritergeek]

I know how to select a pattern for use with bucket fill, but I cannot find a way to make the tiles larger. The GIMP user manual just mentions it's available, but that's about it. I am unable to find anything addressing this. Is it even possible? 

I did scale the entire layer as a workaround, but surely there's a better way. Is there a plug-in for this?
