gEDA-user: promotion of attributes

["Sribalan Santhanam" <sribalan@pasemi.com>]

Is there a way to promote selective attributes in a symbol?

I have symbols with many attributes. I want to promote 

a) the visible attributes 
b) only "some" of the invisible attributes

a) is easy. 

For (b) I know that there is a way of promoting "all" the invisible
attributes. My question is , is there a way of adding something
to the symbol so that I can just promote a selective few invisible
ones?

thanks
