Random Drops in NS

[Konradix]

Since I only ever tried designing levels in NS and not actually play them, I did not realise that enemies actually do have random drops like in the campaign. This actually is a problem for a few levels I want to make, so here's my question: is there any way to manipulate the drops, be it either remove them entirely , set a singular drop or alter the drops? Ideally I'd like for no drops to be present, unless specified, but mainly I'd like to get rid of weapon drops.

@EDIT: If there's no way to manipulate drops, is there a list to see what drops the enemies have?
