Apps Script to combine multiple sheets to a Master and have the Master automatically update if any of the child sheets are edited

I have multiple sheets that I want to combine to a master sheet. I want to have it that if the individual sheets are updated the corresponding value in the master sheet will also update. I can do this with importrange, but I also want it to apply to any new sheets that are created, so that the apps script will update the master with any new sheets created as well.
