Thanks for all advice, sreg_cat in the "execute command after successful build" option does the trick nicely, making sure the bootloader is always included in the hex file.

As Stephan said it comes with WinAVR and was already lurking on my pc. 

If anyone else is trying to do this the correct format, which took me a while to discover, is:
srec_cat <mainproject>.hex -intel <bootloader>.hex -intel -o <mainproject>.hex -intel

It complains about missing start addresses in the hex files which ICCAVR does not appear to provide, but still works ok.
