That's not what you do. You start with an existing symbol file, and  
just tweak it a little. Easy.

How does your plan differ, except by making the process more  
complicated? You have to put the information *somewhere*. For maximum  
ease and flexibility, put it in your project's copy of the relevant  
symbol. You don't need to implement or learn *any* additional  
capability beyond what Hs gives you.

It is cannot any simpler or less error prone than editing the symbol  
file. The information has to come from *somewhere*, the computer  
cannot read your mind...
