Linking channel to an existing reservation

It is currently not possible to connect a channel to a reservation at a later moment or to change a channel since the invoices differ from one channel to the next. These differences include costs, who pays the rent/costs, discount specials and such.

Because of this, it has been decided that in those cases where a channel has to be connected to an existing reservation or the chanel must be changed, the existing reservation has to be canceled and a new reservation must be created.
