Extra G/L periods for year end closure journal entries?

Hi guys,

We are on JDE 9.2 and are currently running a fiscal date pattern with 12 periods (not calendar months, but 4-4-5 weeks pattern).

At year end we are currently booking extra year end journal entries in period number 12. But we would like to book these special journal entries in a separate period number, for instance period 13 or even a period 14.

Is it possible to set this up in JDE? How would the entries in P0008 look like if you would want to add a period 13 and 14?

This is a screen shot of our current settings:

Thanks!
