Custom Format for MINUTES (display X h X m)

Hi all, I've just converted my first Dashboard over from Insights into Explore. Was quite a challenge to get my head around all the new features, but so far I'm liking it, and far better than having to jump into Good Data.

I have one issue in trying to format my results in MINUTES into a custom HOURS & MINS format.

For example, I would like to display/format my Update handling time (mins) metric to display in Hours and Mins as per my screenshot:



In the old Insights we used a string formatter like this: 
{{{||0}}} h {{{0.0166666666666|60.|00}}} m

If this was in EXCEL (and results were in hours first) I could convert with something like this:
=IF(HOUR(C4)>0, HOUR(C4) & " h","") & IF(MINUTE(C4)>0, MINUTE(C4) & " m","")

Given so much of our SUPPORT ticketing metrics are measured in minutes, I'm hoping the product team may add a few more possibilities for displaying time when converted from the standard format.

Cheers,
Dan
