Ignoring Bits within a sequence

It is possible to use the sequence builder to construct an Item from specific (non-adjacent) bits within the protocol.  The following example has been included for reference:

Code@0-4,Code@8-12:S

—where the item 'Code' is a string value composed of bits 0, 1, 2, 3, 4, 8, 9, 10, 11, and 12 within the segment of the current protocol message.
