As of V4.0 of the Modbus_Slave Block Siemens finally came to their senses and now allow to nominate DB areas for Modbus Digitals instead of forcing these onto the PLC's DI or DQ areas. To do so, you need to edit the Data_Area_Array entries (of which there are 8 available) in the Instance DB of your Modbus_Slave Block and attached is the entry straight from the Modbus_Slave Block TIA Portal help. You'll need a dedicated DB for each entry though, but it is small price to pay for this. P.S: This is equally well possible for the Modbus TCP based MB_Server Block too.
