I don't remember where it comes from, but I've used those two shortcut 
for this purpose:


%% Forces MMR to be temporarily expanded
% so that no HaraKiri
% use: Rx \showMultiRests Rx*y \hideMultiRests Rx
showMultiRests = {
 \set Staff.keepAliveInterfaces = #'(
    rhythmic-grob-interface
    multi-measure-rest-interface
    lyric-interface
    stanza-number-interface
    percent-repeat-interface)
}

hideMultiRests = \unset Staff.keepAliveInterfaces
