Maybe some clever user will tell this is already possible. However whilst I am aware that if you click F5 to edit settings for a particular bar you can change volume of all or selected instruments for that bar. However what if I say had a shot on beat 1 and then rest on beats 2 and 3 but wanted the band to start again on beat 4 but quieter for that beat. This doesn't seem possible to set either in Bar Edit settings or in chord options for a bar (Alt-F5)

If this is not currently possible then it would be a useful addition.
