Inserting measures

Hi, I have just started using musescore and am composing for four voices "a capella" . I have figured out how to insert a measure for all four voices at once, but what do I do when I need to insert one for just one voice without adding it in for the others? Is there any way to insert a new measure once all of the voices are composed, for just one voice, in order to fix the timing being off between voices. (I.E.....delete the last measure for that voice and insert it earlier). Can I fix my coordination of measures between voices being off due to forgetting to insert a measure, etc. for one voice, without re-entering all of the subsequent notes for that voice? Any help is much appreciated, it would save me a lot of time.
