You can create, edit and remove the personalized stroke styles for paths. You can define up to 64 system-wide stroke styles. The stroke styles are available in Fred4 in the R&D panel, and in Ted4 in GNML tags. You can apply stroke styles on rules, boxes, frames and image borders on page, and on rules in text.

GN4 supports multiple stripes and hashes.
