Allow interactive editing of sandbox permission requests

What variant of Codex are you using?

CLI

What feature would you like to see?

When the agent asks you if you are willing to approve a sandbox request, you are given the option of allowing commands starting with some prefix to be run without approval in the future. However, the prefixes that are chosen are often suboptimal, either allowing too broad a set of commands to be run in the future or too narrow a range

It would be nice to be able to enter a small editor and decide what fraction of the line will be permitted without further user authorization in the future. It would even be especially slick if one could label particular fields on a line as wildcards (say, unimportant things like a field which always has the names of a build directory and which you are always okay if the agent wants to remove.)
