Expression Fields -> Constants?

When you go to create an expression, the very first set of fields is
Constants with a plus sign next to it. When I click it, however, it says "no
constants available for this property". What is this? What is it supposed
to do? And how does one get it populated?

@.=)Was wondering the same for myself.
We have a deployment issue where the hyperlinks are constants for a site,
but on each report server, the hyperlink could be pointing to a different
location.
( Not a point to a report, but to a web app location )
So a constant that a non-progammer can change would be very useful.
Whilst one can use a parameter as a constant, you have to set this for every
report!
This is painful if you have 50 reports!
A global constant would be very useful.
The other way is to write a dll which points to a text file where you put
your constants in.
But if the Constants collection could be set and used, that would simplify
deployment and even things like setting fonts for headings, could be listed
here.

When you are writing an expression, the constatns section will be there but
will only have values if you are writing an expression say in a background
color property.
To use contants used in all reports use the web.config file. This works
great and makes changing a constant in all reports quick and painless.
