The last time I checked on this there was no parameter, but you could
create one of your own in the templates you use. I would expect the best
place to create it would be within the first datum feature, whether that
be a Coordinate System or a Datum Plane assuming you start your templates
with those features. If I remember correctly you can 'designate' the
parameter which would mean that the part would ask for that value, never
had a reason to do that so my memory could be wrong on those details.
(Someone, please, correct me if I am wrong.) Then in each relationship
you create you would need to place the parameter, and change the value or
use an if-else function to control the value of the parameter.
I know this is a really rough idea, and if I had ever had a need for it I
would have cleaned it up and got all the details right, but we have yet to
use this idea.
