Add the ability to choose internals from the rooming list
The Rooming List can be used to add numerous reservations in one go. One of the necessities of this type of import is to be able to calibrate the reservations in one go also. Thus, if the client chooses that all the persons in the group need to pay their extra by themselves, then the Cashlist internals function needs to be ticked the same amount of times in Commander.
Allow the Rooming List to also populate certain internals directly into the reservations/profiles in order to populate the information in one go.
