Styling: center "modules-center" within available space

[skrattaren]

I'm tinkering with robertjk's config, and my modules are:

    "modules-left": [
        "sway/workspaces",
        "sway/mode"
    ],
    "modules-center": [
        "sway/window"
    ],
    "modules-right": [
        "network",
        "memory",
        "cpu",
        "temperature",
        "battery",
        "clock#date",
        "clock#time",
        "sway/language",
        "tray"
    ],

So the layout is basically:

[1][2]           window title   [sysinfotrayandwhatnot]

As you can see, "window title" is centred for the whole width of the bar, and it really wastes the space between "modules-left" and "modules-center" (due to the number of right ones). Especially when title is too long and can even mess up the layout a bit.

Can I configure waybar to center window title within available space, to get something like:

[1][2]       window title       [sysinfotrayandwhatnot]
