Fill request is sent multiple times when train stations share a linked storage

If multiple train stations have the same storage linked a request to fill it is sent multiple times
So I have 4 train stations that all link the same box. The request to fill it is sent 4 times so when the trains arrive many can't empty and I get the "Train departed due to prolonged inactivity"

I'd prefer the reservations between trucks and trains somehow get shared, I kept my suggestion to that limited scope of the current design but less prone to unintended behaviour.

Actually I don't think Devs should do shared reservations, there's not a guarantee which storage the reservations of a train will go
