Static words i.e. __animal__ = monkey, later in prompt, __@animal__ = calls monkey again.

[MackNcD]

So as far as summoning something and then letting it disperse, as in this prompt;

 [cat : dog : 0.3], [dog : bird : 0.7] 

the inference steps between 30%-70% are where the dog's at, really important for chimera-making, 
to turn on and off something randomly chosen.

I seek a way to put a static symbol on the wildcards, a reference symbol. A new dynamic.

[__fauna__ : __fauna2__ : 0.3], [__@fauna2__~ : __fauna__ : 0.7]
                                  ^
                                  stamp
                 ^--------------
 
There' quite a number of uses, I often go 

~animal~ with a ~color~ fur and ~color2~ spots

 (edit: I've used '~' in place of __, sorry, comes naturally as it's my setting) 

...and then I want the owner of the animal to have that animal's color fur as  his/her hair color, or umbrella color, etc., 
it'd be great if I could add another optional symbol to reference the prior chosen, so 

~animal~ with a ~color1~ fur and ~color2~ spots , 
is walking alongside it's owner 
~character1~, who is wearing a pair of ~@color1~ boots, 
with ~@color2~ laces and ~@color2~ soles, ~@character~'s umbrella is  
~@color1~, with an ~@color2~ handle
