Abroad during Hello Work authorization day (認定日)

As the title says I will be abroad for a friend's wedding during my next authorization day (認定日)at hello work. Generally this is not allowed but is there anyway to move the date to a few days later? Does anyone have any experience with this.
FYI for me it's the hello work in nishi-shinjuku.

Thank you for any experiences / advice!
