Wait time in Hours in subsequence

So with the new subsequences you just added, there is some functionality that I am interested in seeing if you could add to it. There is only really an option to wait for days but there is no option for hours. However the specific thing that I would be looking for is for it to be able to send at a certain time on the the following day. For example, if I mark a lead as interested they will get the first email. Then the second email would be set to send at 9 am the next day. Then the next would be at 12 PM the following day so on and so forth. If we would be able to talk and see how that could be possible that would be great!
