User can configure how much hours is one day, so Story estimate is shown the same in JIRA and AHA Merged

If in JIRA setting, duration of one day is configured different than 8h then story estimate is shown differently in AHA! after importing. 

Example:

- JIRA has configred one day as 7h,
- Story "Story1" is created with 2d
- After import from JIRA to AHA!, this Feature "Story1" is displayed in AHA! as 1d 6h. 

Is it possible to provide configuration options where it is possible to set how much hours in ione day same as it is provided in JIRA?
