Flexible Candidate Time Slot Selection

I would like to know if it's possible for candidates to select exact interview times within a broader availability window, rather than being limited to fixed blocks based on the set interview duration. For example, if a client is available from 8-11 AM for a 45-minute interview, candidates currently see 45-minute blocks (e.g., 8:00-8:45, 8:45-9:30). My team would prefer candidates to be able to choose a specific time like 9:45-10:30 within that 8-11 AM range.
