Gain staging could be so much easier

Presently, if you want to have all your tracks peak at a given DB, you have to run the tracks, with peak hold, then do a mathematical calculation for each track manually, and add/subtract using the gain function.
If there was an auto gain function, bu which you could run a project, then, when the peaks are identified, set, using this function, your desired DB for all tracks, this would be highly useful particularly when setting up large templates. Some composers now use 1000-2000 tracks in a project template.
