Reorder currencies in General tab

Hi. We have implemented a currency changer in the sidebar which lists all ISO codes for supported currencies. Our developer has imported them in the order that they appear in the general tab in your plugin. However, they were added as we thought of them. Now the currencies are visible and in the order in which we store them in your plug in. Is it possible to reorder the currencies in the general tab so they are in alphabetical order?

I don’t really want to delete them all and add them again with custom symbols etc. But also there is no way to drag them up and down the list.

So that’s the question. How can I reorder them?

Thanks
