UPDATE from a SELECT on two fields.

I have been useing an UPDATE from a SELECT on a single field and it works great.

Example:
UPDATE reports.mytemptable SET igka =
(SELECT
CASE
  WHEN value >= 0 THEN value || ' (G}'
  WHEN value < 0 THEN (value * -1) || ' (K)'
END
FROM (
SELECT ((mmpuncorvol - uutuncorvol)::float4 / 1000)::NUMERIC(5,3) AS value
FROM runs
WHERE status ILIKE '%init%'
AND status ILIKE '%fast%'
AND inactive='f'
AND evaluation = reports.mytemptable.eid ) AS idontcare)

To save some time I would like it to update two fields at the same time but I cannot wrap my head around how that could be done. Can it not be done?

I would like to make it do something like this...
Example:
UPDATE reports.mytemptable SET igkrv = mmpuncorvol, igka = givekeepamount FROM (
SELECT mmpuncorvol,
CASE
  WHEN value >= 0 THEN value || ' (G}'
  WHEN value < 0 THEN (value * -1) || ' (K)'
END AS givekeepamount
FROM (
SELECT mmpuncorvol, ((mmpuncorvol - uutuncorvol)::float4 / 1000)::NUMERIC(5,3) AS value
FROM runs
WHERE status ILIKE '%init%'
AND status ILIKE '%fast%'
AND inactive='f'
AND evaluation = reports.mytemptable.eid ) AS idontcare) AS stilldontcare

Any ideas?
