luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase activity

Catalysis of the reaction: luteolin 7-O-[(beta-D-glucosiduronate)-(1->2)-(beta-D-glucosiduronate)] + UDP-alpha-D-glucuronate = H+ + luteolin 7-O-[(beta-D-glucosiduronate)-(1->2)-(beta-D-glucosiduronate)] 4'-O-beta-D-glucosiduronate + UDP.
