A naive sim-side solution, is to just make a unit that has 0 mass/e cost but some fixed buildtime to give it 1 minute in the factory tier you want, the unit would either be scripted to self destruct or you would otherwise hook it away.
"The Right Way" would be to mess with construction.lua in the UI layer, and allow it to manage the queue in a more advanced manner.
The latter option would take a while considering the current state of that file (We're working on making it more maintainable), but the first option would be a quick fix.
