At the moment structure builders can only specify 1 "must have" mod in the mod ID line for dedicated support.

It would be useful to be able to specify a number of mods to allow builders to create structures with multiple dependencies - for example a Davincis Airship made from BOP blocks is currently impossible as a survival build stricture because only Davinci's or BOP could be specified as required.

I am not suggesting that a limitless number of mods should be specifiable, but 2 or 3 would make a great difference to these builders.
