Add Wait/Sleep command to Keybind Manager

[Cheatoid]

When setting up keybinds in Wurst Keybind Manager, is there a way to add a delay (in milliseconds) when doing multiple commands (separated by ;)?

If not, please add it.

For example, if you wanted to say a few chat messages every 500 milliseconds apart: say first;wait 500;say second;wait 500;say third
