Please have an additional filter "Deutschlandticket"

[grince]

Today I tried to find a connection from one city to another, including local buses.
as a filter I used the Netzcard.

this filter won't work since Netzcard doesn't cover local transport.

I expect people with netzcard to have also the Deutschlandticket (since it is cheap and easy to use), so it would be good to have as additional condition to check wether someone has a Deutschlandticket and is therefore able to use local public transport.

Thanks for your work!
