Formatting time tracking balance output as minutes (hledger)

Is it possible to output hh:mm (i.e. minutes instead of fractional hours) via balance --format FMT? Thanks!

With hledger ? No, but it's possible via a conversion rate, like so:

a.timedot:

2025-01-10
foo  ..

b.timeclock:

i 2025-01-10 08:00:00 foo
o 2025-01-10 08:30:00

c.journal:

D 1.0h
include a.timedot

include b.timeclock

P 0000-01-01  h 60m

# or this (and print --round=hard):
#P 0000-01-01  m 0.01666667 h
#commodity 1.m

Convert to minutes:

$ hledger -f c.journal bal -Xm
                 60m  foo
--------------------
                 60m  
$ hledger -f c.journal print -Xm
2025-01-10 *
    (foo)             30m

2025-01-10 * 08:00-08:30
    (foo)             30m

Awesome approach using a conversion rate, thanks! Printing minutes helps in grasping the smaller time durations.
