We have a lot (80+) build configurations, many of which share common/similar properties. In the absence of inheritance of build configurations (registered as http://jetbrains.net/tracker/issue/TW-3350), is there a way to get around this issue?
For example, I tried to change the build configuration xml files directly using sed, which seemed to work fine, but when I tried to edit a changed configuration in TeamCity (after restarting TeamCity) it said "Do you want to save your changes?" before I had even made any changes... I presume from this that a separate copy of the project configuration is kept in the database, or a timestamp at least?
What is the best way to make multiple similar changes to build configurations?
