Can i apply [[awatcher.filters]] rules retroactively?

[tempodat]

Recently added a rule to make Firefox more understandable in the logs

[[awatcher.filters]]
match-app-id = "org.mozilla.firefox"
match-title = "(.+) — Mozilla Firefox"
replace-app-id = "firefox"
replace-title = "$1"

Problem is, now I have two weeks of bad firefox data, with the old app-id and title.

Can I somehow run these replacement rules on previously existing data?

Unfortunately, not really. But you can open the database with a SQLite editor and make an UPDATE query with something similar to REGEXP_REPLACE(your_column_name, '(.+) — Mozilla Firefox', '\1') (don't forget to make a backup before any update).
