API time-offs: get deleted Absences

Hey Personio Team,

we are using the time-offs API for sync to our Resource-Planning tool.
Currently a "TimeOffPeriod" has only 3 states: approved, pending and requested.
It seems like there is no possibility to find deleted Absences. So, the only option is, to check all entries in our Resource-Planning tool whether they are still existing in Personio.
This Method is not very efficient and takes a long time on each check.

Regards,
Matthias Bauer
