Netsys - Splitting sections

Good morning.

This may be a function i am missing but is there a way to split pipe sections? I am creating a header pipe in Netsys Gas and the last part of the header always takes on the properties of the last connection. For example in the schematic below, sections 1, 2 & 4 will form a header with sections 3, 5, and part of 4 being the runs to appliances. However i can only fix section 4 to be the same as the appliance run or the same as the header. 

This is also the case when wanting to indicate pipe reducers on a single section of pipe. is there a way to indicate this?

Thanks,

Daniel
