Out-of-the-box not. But nothing is stopping you from creating some Vbscript (or something similar) that pops up and asks for input which it than replicates to the unattend.xml. Things that are in the inventory for the device can be replicated to the XML by defininng them as provisioning variables and have them injected in the unattend.xml when using the inject script action.
The best tool I use for this is AutoIT. AutoIT is very similar to vbscript, but it has built-in tools for creating GUI interfaces, whereas most vbscript input is limited to a simple text box.
