Override parameter in snapshots dependencies in TeamCity

Question

I really can't get my head around the concept of snapshot dependencies in teamcity (7.1).

We have a build project which deploys the database accordingly to a build parameter (database name and file) and i have a build project which builds and deploys our web app.

What I would like to do now is to chain these two builds but override the build parameter. I found the manual how to access depency build parameters (%dep.btXX.yyy%) but i don't want to access them, i want to override them!

How can I achieve this? I've created a new build in which i trigger the build & deploy and then the database build but it completly ignores my dependency parameters and also I can't change the order of the builds.

Thanks for help!

According to the documentation, it's now possible in Teamcity 9:

Overriding Dependencies Properties

Since TeamCity 9.0, there is a possibility to override the dependencies parameters by redefining them in the dependent build. For example, build configuration A depends on B and B depends on C; A has the ability to change parameters in any of its dependencies using the following format: reverse.dep..

It is also possible to change parameter in all dependencies at once: reverse.dep.*.

The dependencies properties to be overridden can be specified in the parameter names of the dependent build A, either in the custom build dialog or via build configuration parameters.

Pushing a new parameter into the build will supersede the "Do not run new build if there is a suitable one" snapshot dependency option and may trigger a new build if the parameter is set to a non-default value.
