Stock transfer system for brokers (enhancements)

When needed (e.g. if a broker retires), entire customer and contract portfolios have to be transferrable to one or more new brokers. Particular attention has to be paid here to dividing the portfolio according to the expected commission. In the course of the enhancements, it is also possible to differentiate between advisor types when transferring portfolio; in this case, the Excel export is also adjusted. Furthermore, search screens are added to the existing system and filter areas are revised.
