Upgrade/retrofit satellites or drones?

Ive searched countless menus, and read the entire manual top to bottom i think and still have not run across a way to upgrade any quantity of drones or satellites. Its possible that troops and fighters might be similar but ive not played a game quite that far yet.

Is there a way to retrofit/upgrade/change design of these units? Ill start manufacturing a couple, get em deployed (or often not even get them deployed) and then the next greatest tech improvements finish researching, and im left with a bunch of outdated units defending my planets. It can be annoying having half your defending force using lower grade weapons/modules than the other half.

Besides scrapping and rebuilding is there any way to upgrade or retrofit them once they have been built?

Ive also been scratching my head over another puzzlement. Is there a way to select the level of technology that you fit onboard a ship?

Sometimes sending your ship loaded full of the latest technology into enemy space isnt the best of ideas. If the enemy were to attack, disable, then capture that ship, they would have access to technology they might not have. (higher levels of life support, bridge controls, sensors, engines, weapons.)

There are times id like to outfit my ships with lower class technology, for the purposes of deception possibly, or to avoid losing higher tech stuff to the enemy. Atleast thats how im used to playing in other games, im not sure if that would have a bearing in SE5.

If you can answer any questions id appreciate it.
