Launching fighters from docked ships?

Unless I'm doing something wrong, ordering a captained carrier docked with my mothership to salvage automatically undocks it, before it launches salvage fighters.

Is it feasible to allow docked ships (or modules) to fire weapons or launch fighters?

The configuration might be complicated, but it might allow you to design a "mothership" that docked various modules and could effectively launch far more than 120 fighters.

Or could mount far more weapons?

Or for that matter could be configured with different modules depending on mission...
