MS Purchase Orders

It does the basic job, but I really wish there were more ways to further customize the look of the PDF that gets sent out, and change the default email text for all the auto emails that get sent to the suppliers. These seem like pretty simple functions but when I reached out to customer service they said that there's no way to customize those features. If I don't see any updates here in the near future I might just switch to Shopify's native Purchase Order system.
