Hi support   I am  looking for a  plungin to handle the booking  in a proyect  ( this one look's great )  but I have a particular businness rule .    I will have 4 services  in the same location and  I am looking for a way  to show a message ( php or javascript ) if  2 of them are booked at the same time when the third  is bening booked. In order to let know to the user that the place is crowded and so he can decide.   TThere is any hook, action , javascript event of way to do this ? Because I need to acces other services information  to use ...document.addEventListener( 'easyappslotselects',... to show a confirm or something similar .    Hoping to hear from you soon Best regards  Lucas
