I have a service broker application where some parts such as service routes etc must be defined per database configuration, thus certain components change per installation so it would be nice to tag such items as TO DO items, like wise once complete when comparing to latest or changes the item is not displayed as an object that has changed.

Going further it might be nice to populate table data that also configures per installation as well

perhaps use of extended properties, or a file present in source. I had taken the source code and placed a comment in it hoping it might at least show up during sql compare or getting latest code, didn't work on database level objects
