Possibly Adding the Signal Parameter to some Interrupt Conditions

[capitaine7412]

Hello. I was tinkering a bit with some train and I wanted to make a train go to multiple provider station to get some resources for some kind of train-based mall via interrupts (via receiving a signal of those resources). But I didn't wanted for the train to go and get actual full train of resources, I wanted to put some sort of threshold to it, but the only parameter available for the item count wait condition is the item parameter and not the signal parameter. I was wondering if the signal parameter could be added for some of those wait conditions (considering the train can already read that value in the interrupt condition).
I Was thinking about that kind of interrupt in the screenshot for those trains.
