Blocking 0.25 increments of a day in Other Events, or Holiday & 1/4 days in Sick days

Not all companies deal in 0.25 increments.
The system does not allow you to block the 0.25 increment being an option if the company does not use it.
Employees are not precise and use Days or Hours. When choosing to use Days tin either Holiday or Other Events that stipulates Total Duration. It seems that employees are able to amend this and add whatever percentage of a day they wish, from 1 to 0.80, 0.75,0.50,0.25. 0.10....whatever. If it Manager when approving does not notice that, it is then incorrect in the reports. Causing extra work or issues to untangle. A employee should not be able to change this part, they are not best suited to decide what amount of their work day amount to above mentioned amounts. They either leave it as a day, or go to the option of Hours.

The same with Sick days Planner which gives the option of 1/4 day, which if a company doesn't have, and it cannot be blocked causes issues and more work.
