There isn't really a straightforward way of identifying that as far as I'm aware. Using the Squeeze Opportunity filter will not limit it to only one caller, and the number of callers before an action isn't stored in the database.
If that is something that you really want to dig into it may be possible to work something out using an expression filter in My Reports
based on the amount faced as a percentage of the pot (cash_hand_player_statistics.val_f_2bet_facing_pct), although there could be a few complications in the calculation there depending on if anyone previously limped or posted blinds out of position, or if the player with the squeeze opportunity is in one of the blind positions.
As an example rough calculation (off the top of my head) if there was an open raise to 3BB and a single call then there would be 7.5BB in the pot and you would "face" 3BB, so I would expect cash_hand_player_statistics.val_f_2bet_facing_pct to be (3 / 7.5) * 100 = 40%. (You may need to experiment to see exactly how that works, though.)
