I believe that some gestures & swipe actions are being worked on for the upcoming release or a future release for mobile specific actions.
As for your question... I reckon it would be possible to implement yourself by adding a button hold action to each of the items in which you set item (tick item dragged) & then in the game tab > mouse properties in mouse release action add something like:
-- these are action parts not lua script!
if item below cursor exists
pause for 500ms
...this will automatically clear the item as soon as you release the left button or if an object exists below the cursor then it will wait 500ms before clearing the item which should give the system enough time to execute the dropped item on object action. If you are including the clear item in the object actions instead then you could just include an if object doesn't exist & clear item end if instead in the mouse release actions.
Hopefully this helps get you on the right track
