Adding a one-measure time change should not affect the rest of the song. I wanted to add a beat to a measure in the middle of a 4/4 section. When I added the 5/4 time signature, the system moved the end of the bar one note to the right producing a 5/4 measure and changing the next measure to 3/4. there was nowhere to put the new note that I wanted. What I wanted and expected was for the system to add a quarter rest to the end of the measure in question and a 4/4 time signature in the next measure without otherwise changing it.
