No crude oil symbols in train automation?

Apologies if this is a dumb question. I literally might be overlooking a UI element here.

I'm transporting oil with fluid wagons to a refinery. I want to tell my train, "Leave the station when you have more than 2k crude oil", but as far as I can tell, I can't. Crude oil isn't a resource option in the "Inventory greater than" selector, unless I'm just not recognizing it. Crude oil barrels are, but I'm not barreling the stuff. I'm shipping it raw.

Am I missing something obvious? How can I get my train to leave the station when my fluid wagons are full above a threshold?

Fluids aren't items. You have to use the fluid count condition.

Ah there we go. I just completely missed that UI element, and was used to finding the liquids in the resource menu intermixed with everything else.

Thank you.
