Feature request: titles for stackline icon windows

I'm using yabai with Uberischt & simple-bar and while stackline is a fantastic addition, it would be great if the stackline windows could have a title set so that I can filter them out of the open windows shown by simple-bar. Currently, it looks like this (this example is chrome, slack and discord in a stack):

I can filter out windows by app name or by window title, but the app name is apparently Hammerspoon for these windows which would also filter out, say, the hammerspoon console which I don't want. And I can't filter by window title because the title is empty:

{
    "id":9853,
    "pid":79790,
    "app":"Hammerspoon",
    "title":"",
    "role":"AXWindow",
    "subrole":"AXSystemDialog.Hammerspoon",
        ...
}

Could the title be set to something like stackline or something starting with that so that they can be easily filtered?

And thanks very much for making this!
