Can I define two adjustment period per a month?

Content

Hi, 

I want define two adjustment period per a month.

For example--------------------
May-2021_Before  --this is adjustment period
May-2021             --this is normal period
May-2021_After    --this is adjustment period

Jun-2021_Before    --this is adjustment period
Jun-2021              --this is normal period

So I tried to define the calendar, but an error occured "You entered quarter numbers that aren't in sequential ascending order by period. (GL-781849)"

Please tell me can I do this setup?
