Put 'Display Own Custom Pkg Features' Per Package Basis

I want to add some Custom Features only to one of my packages. When clicking the current “Display my own custom package feature list captions” this applies to all packages (that I can see anyway) and so I have to manually type in all features on all packages and tick them on or off when using this option.

It would be awesome to have this feature on a ‘per package’ basis so we can save a bit of time.

Unless, of course, I am missing something and there is already a way to do this, if so, may someone please advise me how! 🙂

Thanx!
