I'm not sure what you mean by 'circuit pattern closed at alternating ends'. You may want to manually create part of the pattern, then copy/paste and edit any locations around your tamper circuit or create a dynamic shape using a fill style of Xhatch.
I hope this helps. If not, please attach a file with a picture showing what you are trying to accomplish so we can help you out better. Thanks!
