Non No-Drop server question

[Baruuk]

I posted this previously in the General forum section and perhaps it was the wrong spot. I'm considering building a server soon and one feature I'd like to incorporate is making nothing "no trade" (making everything tradeable), except for perhaps epic weapons and certain quest items. Now that I think about it, I'm certain I've seen this done with items on Stormhaven, etc. Is this done with a general setting in server setup or is it done by individually setting each item's no-trade flag, etc.

Thanks in advance!
