In our opinion, the stamping of multi-feature sets could be better designed. Instead of always carrying out the stamp process several times (e.g. allocation of invoice items/partial amounts to cost centers), this should be carried out within a stamp process. For this purpose, during the stamping process, a multi-characteristic could be provided with a (+) symbol, which, when confirmed, makes the corresponding multi-characteristic set available again. In our opinion, this has optimized the stamping process and also offers good combination options with other wishes expressed here, such as calculation features. Example: Distribution of an invoice amount until the entire value has been distributed.
