Is it possible to make something that lets you buy more ships easier? Like, If i want to buy 10 ships of a certain preset. So that I don't have to click so much just to buy 10 ships of the same loadout.

Are you asking for a built in version of this? http://www.voupr.com/plugin.php?name=shiploadoutsmanager

Set it up as a preset, then just click the preset 10 times.
