Courtesy Time Signature before repeat

I am currently in the process of transcribing a piano accompaniment track for a piece with a fair few time signature changes and have run into an issue with a repeat. See, the first time through, the piece goes back to a previous bar that has a 3/2 time signature, however the second time it goes on to a 7/4 time signature. This is shown in the original through a first and second time bar, with a courtesy time signature before the repeat, however I cannot get MuseScore to add this courtesy time signature at the end of the first time bar. Any ideas?
