Autorun scripts after JOSM start

[ghost]

My script is intended to be run by key shortcut. When it runs it creates menu item, i.e. new JSAction(... with onExecute: function() { run_this().... However, while shortcut assignment persist over the JOSM restart, I need to run create menu item script each time after JOSM starts. So, the question is if there is some feature how to run scripts automatically after JOSM start?

Option for multiple autorun scripts would be great as multiple items are added by different scripts.
