Can anyone advice how to splitt (and sum) energy streams in Hsys?

In Hysys exists a convenient method to obtain a generalized energy stream e.g. as

the condenser duty of distillation columns.

I need to divide this energy stream into one part used for heat integration

the same modelled plant complex and another less interesting part for external use.

I tryed to use a spread sheet to do this, however this causes consistency problem

with and without involving a balance block.
