The Leave Request on Parent Portal

The Leave Request on the Parent Portal gives the parents also the option to mark their child from 00:00 to 00:00 on the same day many parents just use this instead of whole day).
If they do so the absence can be aproved in Registration Manager and it can be seen in Out of School but not in Period View. Therefore, the teacher who's taking register has no information that the concerned student is excused and will mark him/her absent.
Is there an option to change the default time setting on the Parent Portal / Leave request to 00:00 to 23:59.
