Is your feature request related to a problem? Please describe.
Many data required for tax purposes are available automatically via ODB2 (e.g. mileage at start/end of a trip, fuel consumption, locations). It would be great if they could be utilized to automate collecting them for that purpose.

Describe the solution you'd like
Collected data could be used to pre-fill a drivers log. See this photo of a German paper book for this purpose:

Columns translated:

• date
• time (from/to aka trip-start/end)
• route/target, purpose
• purpose / visited companies, driver / occupants / cargo
• mileage at start
• mileage at end
• driven kilometers (business, private, home/work)
• fuel (litres, cost)
• oil (litres, cost)
• others (cost, purpose)

Many of these fields could be pre-filled via ODB2-collected data. Some others could have often used values prepared (like often visited companies/locations or routes/targets). Not all of them are even mandatory – but have as much data as possible gathered automatically would be a tremendous help already – especially against forgetting to write them into some entirely manual "solution" like a paper book.

Describe alternatives you've considered
A paper logbook (inconvenient, one tends to forget). A separate app (found no FOSS app for it).

Additional context
This would be a nice complement to using the app as dashboard. Thanks in advance for considering!
