Global scaling in Designer

Hi Bill, I know the app has a scaling feature. But I find that most but not all my elements fall into place when scaled down, in my case to 89%. The need to scale is to accommodate a new tablet that has a different screen dp. I find I need to go into designer and move elements out of place to make them render in place in the app when using a scale factor. Both my tablets have the same aspect ratios of 16:10, but different dp’s

I was thinking that if i could use the dp of my new tablet in Designer and be able to scale the whole project within desiginer rather than having to scale each element individually it would be a huge help.
