Possibility to book same interviewer for Overlapping slots of the interview

Summary:

Is there a possibility to have overlapping interview slots for the interviewer for Candidate Managed Interviews?

Content (please ensure you mask any confidential information):

We are using Candidate Managed Interviews and are creating two interview slots that are overlapping in nature (For example- 1:30 TO 3PM and 2:30 to 4PM). The interviewer is the same in both cases. When one of the candidate books any of the slot the overlapping disappears from the system which was initially there while creating slots? However when we choose different interviewer and the candidate books it, the overlapping remains in place.

Is there a way we can enable overlapping for the same interviewer? This is needed because the slots are for 1.5 hours and the candidate has to appear 30 minutes before the interview actually starts.
