Lumira Designer auto height and width always equal ratio

Dear experts,

I'm trying to achieve Lumira designer layout which height and width ratio should be always same but should expand based on screen size. After setting up grid layout's height and width as "Auto", the current design behaving like figure 1 and figure 2 in below picture.

But I need to achieve something like figure 3 in below picture meaning that the proportion of height and width should always be same even though screen resolution changes. The need is our customer using power BI and they are expecting same functionality on lumira designer

Please note, I got some threads related to auto resizing but not related to my requirement.

Regards,
