Copying multiple time signature changes

I suspect this might have a really simple answer but I can't seem to work it out..

I'm working with a 16 bar section in the arrange that changes time signature every bar or two - all working fine with changes showing in the global tracks area. How do I copy this section in the arrange while also copying the appropriate time signature changes? My normal copy/paste routine doesn't copy the signature changes as well.

Thanks,
D
