This principle is well-known in electoral science where it described by the French term "apparentenement". It has been used in party-list PR voting systems at different times in France, Italy and Switzerland. In France and Italy the "apparentenement" was determined by the parties. In the (much) more complicated Swiss system, the "apparentenement" is determined by each individual voter. The allocation of seats to parties is determined by applying either the d'Hondt formula or the Sainte-Laguë formula to the votes, summed over the "apparentenement" partner-parties as necessary.
