Space platform Interrupt trigger based on planet requests?

[engineeringftw]

I have a Space platform hub (ie, a ship) which has 450 uranium cells on it.

On Vulcanus, Gleba and Fulgora I have a request for 150 uranium fuel cells in the Cargo landing pad.

If on any of those three planets, the requested uranium fuel cell count is less than 150, I want to have an interrupt that is triggered by the request for 150 uranium being unsatisfied on the planet, and have the target planet added dynamically as a temporary stop, and have the ship travel there and wait until the fuel cell count is at the requested 150. I want to do this without having Vulcanus, Gleba and Fulgora added as permanent stops. Is this possible?

Said another way, I want to trigger a temporary stop being added based on a request from a planet?

Only interface between space and planets is via rockets. No signals or other kind of information can be transferred. Meaning: No, you cannot have an interrupt that waits for a signal or anything "from the planet".

What you could possibly do: Keep a platform in orbit, satisfying planetary requests - once the platform cargo is below a threshold, it can trigger an interrupt to fetch a resupply from somewhere else.
