Change default overwrite behaviour

Hi,

 When you first do an overwrite edit, Premiere asks you what you want to do i.e:

Change Clip Speed (Fit to Fill)

Trim Clip’s Head (Left Side)

Trim Clip’s Tail (Right Side)
Ignore Sequence In Point
Ignore Sequence Out Point

I clicked the wrong one and also ticked the "remember for future" box and now for the life of me can't work out how / where to change this default. It's driving me crazy! Does anyone know how to change this?

Thanks, 

Paul
