We discuss how this can be used to extract information on modified GW propagation, which is a crucial signature of modifications of gravity at cosmological scales. We show that, using quadruply lensed systems, it is possible to constrain the parameter $\\Xi_0$ that characterizes modified GW propagation, without the need of imposing a prior on $H_0$.
