whm, Reseller setup (global or not owned)

[DefiantPc]

Our first whm/cpanel server
Setting up a reseller account in WHM and come to this checkbox:

Disallow creation of accounts with packages that are not global or not owned.

What does this mean?

whm/cpanel seems so much harder than Plesk and their documentation is cruddy can't I just set up the reseller accounts in telnet/ssh?

It means that they must own the package or the package must be global *aka everyone can create it*.....

I find it way easier just to point and click to create a new account...
