You can ignore the provided values, collect your own and summarize
those. Granted, this is sub-optimal.

There isn't.

But here is an idea: `org-columns-summary-types' could also accept
entries like:

  (LABEL SUMMARIZE COLLECT)

where COLLECT is a function called on each summarized entry. SUMMARIZE
is applied on the values returned by COLLECT. When not provided, COLLECT
default to `org-entry-get' as it is the case already.

WDYT?
