Question / Help Sub Window Recording

[Sicx]

Hello everyone,
I want to record a sub-window of a program, but can't find it under window recording, I can only record the main window of the program, and when I open the sub-window it doesn't show up in my stream preview. Is there any way to do this?
Here are some pictures to clarify what I mean:

1. Main Window:

2. Sub-Window:

I want for example only the "Exp Meter" but it's not shown in my OBS and also not as a seperate window in my taskbar.

Is this possible?

To my knowledge if you have it set to window it will only record the one main window. However what you can do is use monitor capture and crop it. Right click on source go to transform and edit transform.

The only disadvantage to this is if you move the window will be recording the desktop.

Yeah I tried it with cropped monitor capture but I hoped there would be a more elegant way, because I have to move it to the same spot everytime or change the crop everytime. I think I have to live with that
