Sequence Function based on 2 values

Hello Excel Community - Not sure if the sequence function can do this, but I figured I'd ask someone smarter than I.

I love the Sequence function!  I am using it for Levels.  I enter the number of levels, lets say 12 and on my back up page, I am able to create rows 1, 2, 3...through 12 (or whatever value I enter into a specific field).

Now my folks are asking for further sequencing....now they are looking for zones.  If 3 is entered, the rows should be created;

1-1

1-2

1-3

2-1

2-2

2-3

3-1

...

12-3

I am not sure that the sequence function is the right thing to do, but also not sure what function will do what I am looking for.

Thank you in advance, Excel Gurus!!!!
