Is there a way to set a large number of coins as available for swap?
It's easy, just say you have many coins available for a swap, and if the coins are in an Excel list, just say so, and ask people to give you their Email addresses, and then send them your list, that's how I do it! So if you have those coins in an excel list just send me a PM and I'll answer you with my Excel list!
Take care and enjoy
