You sure you tried with and without “context sensitive” checked?
Try making your system on the eventGraph without using macro and then select all the nodes, right click, collapse to macro, and see if it works.
Also, you can copy/cut and paste nodes ( Ctrl-C/Ctrl-X, Ctrl-V ), so if you can insert a delay node outside of the macro, just cut, paste it into your macro.
