Best way to input times

Hi Drew,

I need to enter a table of opening times. I've currently achieved this by have a number of content type="select" in a repeater. I have a select for each of the following the open hour (1-12), the open minutes (00, 15, 30, 45) and time of day (am, pm) and the same again for the close times.

In the admin these all appear on separate lines is there away to group them, in a similar way to date?

Regards - Nick
