Ability to set default value for 'Override Time Spent' field when adding Worklog

We use both the Calendar and the Daywise Worklog views to add worklogs, and then use the 'Override time spent' field to set the time spent.

In Calendar, the default value is 00:00 In Daywise Worklog, the default value is 01:00

We are logging work simply in 1d blocks (8 hours), and a customisable default value for those screens would save a lot of time.
