QSYS file changes without GUI

Hi,

I am wondering whether there is a quicker way to handle my design, originaly built with QSYS GUI, without going through the whole proccess each time.
i.e. if I want to replace a file with a new version - when I worked with regular project's' I just added the new file, and removed the old one (and keeping the module name).

is there an easy way to do such a thing with a QSYS system?

Thanks,
David
