It appears that the only way to create a dependency is to use the mouse to link two items together in the gantt view, or to open up the task and specify item relations (via the mouse). Would love to have a shortcut way to just type in what I want in terms of the link: a field or cell that lets me type in the item id and specify the dependency type. for example, if I type in "HAWO-1FS", a "waiting on" dependency gets automatically set up.

This would allow me to quickly type in all of my dependencies across my plan. When plans get large (300+ rows) and we need to add dependencies for each row using the mouse becomes very cumbersome.
