Yes, since these sets are built in sequential blocks running from 1501-1525 through 1726-1750, you can combine adjacent ranges together to build a continuous numbered index that extends well beyond what any single set covers on its own. Confirm that the style, tab color, and printing format match exactly across the different sets you're combining, since mixing visually different tab styles within one continuous document can create an inconsistent, unprofessional look even when the actual numbering sequence lines up correctly. Browsing the full number tabs range helps confirm which adjacent ranges are offered before committing to a large combined order across multiple sets.
