Can I apply this to mouse actions?

[nathan323]

In Default (Windows).sublime-mousemap:

`{
         "button": "button1", "count": 1,
      "command": "chain", 
      "args":
      {
        "press_commands":
        [
            [
              "drag_select",
            ],
            [
              "hide_overlay",
            ],
        ],
    },
},`

I tried the above withpress_command (the usual syntax in .sublime-mousemap), instead of command, still didn't work. Is there any way to modify the .py file to include mouse support?
