Add task setting to set default date

[XotEmBotZ]

Is your feature request related to a problem? Please describe.
It is a bit tedious to set date every time you have to create a tast

Describe the solution you'd like
A setting in the tab 'task setting' which will set default task date to 'today' , 'tomorrow' or 'n days from today'
*last one is optional

Describe alternatives you've considered
Update the task one by one manually
Use the select feature and update it
(fails when using nextcloud #1504 )
