I've got a circuit system set up where if a current network is missing some items that the logistic network needs, it would request these items from another logistic network.

Similarly, this is also used in my auto-assembler system. Missing logistic items such as inserters, or assemblers, especially on Fulgora, are automatically requested, crafted, and supplied.

However, the problem is that whenever I place ghost blocks down that the logistic network doesn't have, it wouldn't be read by the network as missing. Therefore it won't be supplied.

As a workaround, I have to always have a buffer chest in place that would include nearly every potentially needed entity for the logistic network to fulfill to prepare for building ghost blocks, but with it comes another problem: resourcefulness. On Fulgora, with the limited space and how expensive higher quality machines become, requesting them could bottleneck the entire system when they aren't yet needed. I might require rare inserters before a rare electromagnetic plant.

Honestly, with 2.1 coming soon and the logistic requests option coming from roboports, I'm surprised this wasn't slotted to be announced today. Hopefully next FFF!

This information simply isn't known by the engine to putout anywhere. The alerts you see are only accurate at the instant the alert is created and the game only checks a few ghosts per tick to see if items are available to build them.

You can observe this in the map view as the alerts move around the ghosts.

Additionally the alerts are only relevant to a single logistic network - but multiple networks may overlap a given ghost.
