Each rule decides which Itemcodes can carry a punching suffix on dyc:Name (e.g. C25019 35w/250w/465w/4557f). Match by literal prefix (C25019) or a /regex/.
Click any chip to start a new rule with the itemcode pre-filled. The trailing P / U punching flag is auto-stripped at match time.
Stable identifier — used as the JSON filename. Defaults to the pattern.
Optional — shown in the list.
Literal prefix matches case-insensitively against the Itemcode (after stripping the trailing P/U flag). Wrap in slashes to use a regular expression: /^C\d{5}/.
