Is it possible to write Custom duplicate check on PAN during onboarding process

Summary:

Hello All,

There is requirement to validate PAN number against active employees only while onboarding a worker and restrict continuation of onboarding if found there is duplidate. We tried to look into autocomplete rules. However, we are unable to include custom value set in auto complete rules to perform this validation.

Do we any option to do this or any other solution is available to do this validation and restrict onboarding if there is duplicate PAN number with active employee exists in the system.
