Detail boundary

[OBERMEYER]

How can we get the detail boundary of a callout to match as setup to fit a sheet layout? If they don't match then every time we rebuild the detail it throws off all the setup work we've done to lay the detail out in a sheet.

See screenshot.

There is one command (item 2 in screenshot) that reads " UPDATE LINKED MARKER'S BOUNDARY" but that must be for some other purpose.

I suppose we could copy the layout dimensions setup and then scale and paste on a layer to hide in the section view and then line up the callout boundary there but this seems like a lot of work.
