[Feature-13043]Perspective - Dock size as a percentage?

Is it possible to open dock size as a percentage? I am designing a mobile project in perspective and hoping to have a bottom dock appear after an item in a list is selected. Since pixel count can vary so much in mobile devices, it would be nice to be able to set this dock size as a percentage, instead of pixel count. As far as I can tell, this is not possible currently (if I enter 50% into the dock size portion, it removes the % sign and acts as 50px).

To my knowledge it is not currently supported in the application, but I’ll open a feature request as I don’t know why we couldn’t do that.
