Editing a Drop Down

Don’t judge - i got a little carried away - so my cropping list is out of control - now I have a better idea of what I am doing and what I actually need - is there a way I can edit this list and start again?

Many thanks in anticipation.

To delete a custom preset, hold down the option key while clicking on that preset. ( Crop Tool - ACORN 8 DOCS )

Best regards

Thank you so very much - worked like a charm.
