Adding more thunderbird kde direct shortcut(new event, show calendar etc.)

Hi,
When adding “Thunderbird” as an application in the shortcut menu, you get only 3 shortcuts : 1 for new mail, 1 to open the contacts, 1 to open thunderbird.

Do you think it could be feasible to add 4 more shortcuts ?
-1 to open the calendar page like it is the case already for the contact page
-1 to open the task page
-1 to create a new event
-1 to create a new task
