Ability to manually enter custom location while scheduling interview

Hi,

Curious if anyone has faced this before … we have a need for hiring managers to have the ability to enter location details for interviews for locations that are not in HCM, how have other clients achieved this requirement in the past? Currently the address that is generated for the candidate is based on the location that is selected in the controlled list of values in the drop-down list, which returns only locations that are in the Core HR locations table.

We need to be able to manually enter the location address details for the candidate as the interview could occur offsite at a non-hcm location, but I cannot figure out a way to do this as there are delivered fields that appear on the candidate view on the external careersite that would contradict the user experience currently.
