For the fields you can set to DropDown with Dependencies - is there a way to nest those further instead of only having Values and Children?
For example if we wanted:

Value: Request Type = Computer
Child Value:Hardware
Sub Value -> Monitor
Keyboard
Mouse
Etc.
Child Value:Software
Sub Value -> Adobe
Sub Sub Value -> Reader DC
Pro
PhotoShop
Etc.
Sub Value -> Microsoft
Sub Sub Value -> Outlook
Word
Excel
PowerPoint
Etc.
