Midi keyboard notes all in treble cleff

Hey there, when i use my midi keyboard to quickly add notes they always pile up into the treble cleff which is particularly annoying when im using both hands, (it gets messy).

Is there a way to easily to have notes below middle C to go in bass cleff, and vis versa?
Or an easy way to just split them up into treble and bass cleff when i go back to edit it?

Thanks heaps,
