This may be possible already: https://github.com/simonw/sqlite-utils/blob/396f80fcc60da8dd844577114f7920830a2e5403/sqlite_utils/utils.py#L311-L316

And yes, this does indeed work - you can do something like this:

```
echo '{""name"": ""harry""}' | sqlite-utils insert db.db people - --convert '
import time
# Simulate something expensive
time.sleep(1)

def convert(row):
    row[""upper""] = row[""name""].upper()
'
```
And after running that:
```
sqlite-utils dump db.db 
BEGIN TRANSACTION;
CREATE TABLE [people] (
   [name] TEXT,
   [upper] TEXT
);
INSERT INTO ""people"" VALUES('harry','HARRY');
COMMIT;
```
So this is a documentation issue - there's a trick for it but I didn't know what the trick was!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1178546862,
