Scripting 2 file web export?

[ono]

Here is my common scenario. I make a iOS app UI element design, save it as UIElement.pld, now I want to export it into two PNGs UIElement@2x.png (100% scale) and UIElement.png (50% scale) in the same folder PLD file resides, problem is I need to click really a lot going twice through Web Export window.

Would it be possible to create an PhotoLine Action that will create me %FILENAME%@2x.png and %FILENAME%.png with single click somehow? Can I do it writing own plugin, using AppleScript anyhow. I am bit tired of repeating same actions all over again whenever I change a little thing and I want to test it.
