dragging items via verbcoin

I know it's possible to enable dragging in the game properties and it will work automatically, if you left-click an item. However, I am using a verbcoin interface and I want to know if there is a way to start this method manually, because I'd like it to be triggered by the "use" command of my interface instead.

The build in dragging should work.
You need to tick the box "items can be dragged with this command" in the command properties of your "use" command. (If you don't want any other command to drag an item see to it, that the "use" is the only one where the box is ticked.)

If you want to trigger it completely manually: Use the action part "set item" (under interface category) and tick the checkbox "dragged item"

Thank you!
