I am trying to implement custom scripts specifically on the offboarding page for the second part of the process(Reclaim Assets). 

Our imported assets have a naming standard, usually follow PREFIX-Serial#. We want to make it easy for the user to complete the form by changing the displayed name from the above to Laptop without actually changing the asset name in our inventory. 

I know how I can achieve this using JS but unsure where I can put the custom script under portal designer :(

I’ve tried footer page and have had no luck. I assume this page is a public page and scripts implemented under portal designer do not apply? But than again, I have to sign in to access the page so I assumed this was not the case.
