copying instrument changes

i know that musescore is not supposed to be a soundcentralised software, but this particular problem, nevertheless, annoys me. whenever i copy a fragment that includes instrument change, only everything else will be copied, but not the instrument changes. which really sucks, when i try to mimic somehow a guitar playing "x notes", because for every note, in order to sound a bit like there is just plcuked, damp string, i have to initiate an instrument change. which is all right, but not being able to copy those changes just makes everything ridiculously complicated. i am not complaining, really cool that this software exists, but if someone has an idea how to simplify adding like five instrument change for every measure, regardless, if the measures should be the same, please share.
