Mastro did break their high-grade 1954 Wilson Franks set up into three or four lots last year, as I recall.
Also, please do not forget their Spotlight Auctions in the 2000/2001 time period. Basically they took the 1950s PSA-graded sets of an advanced collector and sold them on a card-by-card basis solely through their online auction entity. It seemed to work very well for them at the time - but the sustainability of that was ensured by a supply of a six to ten sets that were able to be broken up and sold separately. It would not work so well on a one-off basis.
Also - I'm pretty sure that Mastro has had very large single card runs from the 1915 CJ set and the 1933 Goudey set in the past. Perhaps not entire sets - but dozen and dozens of high-grade examples that were sold individually.
