Hi,
You can "cheat" by having a recipe that does all exports but does not actually write to its output (the output is "dummy")
The reason for that is the concept of the DSS Flow: in DSS you always "build" one output rather than "running" recipes. In order to build output, DSS recurses the dependencies graph to check for up-to-dateness. If there were two recipes writing in the same output, DSS wouldn't know which part of the dependency tree to use
