drag and drop with functions#1406

Hi Team! A great feature of Tasksboard is sorting with drag’n’drop. Is it possible to add a feature: drag and drop of one task (directly) on another task which than get the newest due-date [this is helpful if you have older unfinished tasks and would like to give them a future due-date].
And an advanced feature: while placing one task on another, you automatically get the options merge, get newer date, …[etc] and the option you chose is saved for the next time you drag’n’drop one task on another …
