Make windows take sepcific position after startup while using dwindle layout

[Elekam]

Hello,

I currently have the following in my config:

exec-once = [workspace 1 silent] firefox
exec-once = [workspace 1 silent] $music
exec-once = [workspace 1 silent] $terminal

I would like these apps to open in a specific layout.
Firefox left, music player middle and terminal right for example.

But the terminal always takes the left spot because it starts the fastest. Music is the second fastest and would probably always spawn in the middle too no matter what I set.

How can I tell these apps to position themselves in a specific layout? Is that even possible or something planned in the future?

I imagine it might be incompatible with the dwindle layout in general but not sure.

Thanks in advance for any advice on this :)
