Perhaps there is an easy way to do this that I'm missing, if so, let me know!
Otherwise - The TEC and the Vasari have resource boosting econ structures that are fire and forget; you build them, they do their job, you go back to other matters.
The Advent however, require a very annoying bit of micro. In order to use their resource boosters, you have to zoom down to an individual system, and manually toggle individual trade ports to resource focus.
Could we please get a system level button to cycle the trade ports in that system? Just a simple left click to increment, right click to decrement would work great, and allow you to change focus throughout your empire as needed to boost credit or resource income.
