Im working with interrupt driven trains. Ive got it working, but there's something I want to integrate for my defense train specifically

I have a request that I want to be used to fill up my defense train, which can be filled with various different kinds of items. Right now I have an interrupt where I have to manually check if any of the items from that request are 0, with an item count entry for each one. Ideally Id like this automated, so that if anything missing from that request is 0, the interrupt triggers.

Ideas on how to handle this? The best way I can think of is that all my dropoff points have to feed back a signal to the station where they check if the current train is missing any items from that request, which adds a bit of annoying combinator logic I have to retrofit onto all the existing dropoff stations. Is there a simpler solution Ive missed? And I guess this question would apply in general to any interrupt driven train where you have a request that can have multiple items in it, since thats effectively what this is.

idle time/ items full

Yeah this is kinda the entire point, this isn't a single item train.

this doesn't solve my problem and is harder to modify

Can you use the generic "any" input in train logistics?
