Boolean Custom Fields

[YADOAK]

I have created a custom field (CP-1) on grass land (in Griffin, Indiana) but Courseplay won't recognise the pond. I have created a second custom field (CP-2) around the pond but i can't see how to subtract CP-2 from CP-1 to have Courseplay avoid the pond. Can this be done?

Islands are not supported for custom fields. It won't work.

How about the road goes to and around the pond here, then create the field like a horseshoe? Should then be ok

I would rather plow the field and make a real grass field (not drawed grass) if I want to work on it more often.
Maybe plow the outer border and the island.

Yes! That would work better ;)
