To automatically assign all track inputs (of the same type and channel width) to unique ascending Input paths (cascading):

Command-Option-click (Mac) or Control-Alt-click (Windows) the Input Path selector of the left-most Input Path selector and select the first Input Path (mono or stereo, depending on whether your tracks are mono or stereo).

All visible tracks of the same channel width (mono or stereo) are auto-assigned to unique Input Path assignments in ascending order. For example, Track 1 to A1, Track 2 to A2, Track 3 to A3, and so on.
