I require two changes on the Support portal application,

1) The data generated via report for elapsed time is in the format of HH:MM:SS but we prefer it in days

EX: The output which I get will be in 288:53:30 but I need it as 12 days:Hours: Minutes

Is there a possibility for this

2) I have created a new field((pick list attribute) in "time entry" for a support rep  I need it make it as mandatory field. 

Thanks for your assistance in advance.

Thanks,
Naveen
