Required where a string has an unknown number of parts separated by a delimiter that needs to be parsed from end to beginning to identify the individual elements. Common need for us when parsing and standardizing street addresses. Alternative would be to add option to existing action split delimited text to find/keep text after last occurrence of delimiter rather than assuming first instance.
eg string: 1201-100 OLD YONGE STREET, TORONTO, ON M1P3J3
