Addition of time in Scheduler > Availability Chart

Hi,

Firstly, apologies if anyone has already asked for this........

If at all possible, could you please add time functionality within the Scheduler > Availability Chart.

If, for example, I wished to take tomorrow off and am returning Monday morning - ideally I only want it active and sending any incoming emails to my selected rep in my absence, during the times I am actually not here, being from 5pm tonight 15/09/16 until Monday morning 19/09/16 8.30am.

The way it is at present is I can only either turn it on when I leave 5pm tonight and turn it off on my return Monday morning 8.30am, or if I want to make sure I don't forget then choose from the 16th thru to 19th - but then it won't capture emails from tonight and will only start tomorrow 16th.

I hope this makes sense, essentially I'm asking if it could be the same as Outlook Automatic Replies (Out of Office), as below:
