How to combine application and bootloader in the same ZIP file

Question

Hello, 
 I'm using SDK15.3.0, softdevice S132 v6.1.1 and we would like to know if it is possible to combine the application and the bootloader in the same ZIP file in order to perform only one DFU. We have several boards to update and it could be quite long. 
 I saw this threah : https://devzone.nordicsemi.com/f/nordic-q-a/24347/combined-bootloader-and-application-update and it seems it wasn't possible with the previous versions. 
 I tried the following command : 
 
 nrfutil pkg generate --application master_app.hex ^Capplication-version 304 --bootloader master_dfu.hex --bootloader-version 1 --hw-version 1152 --sd-req 0xB7 --key-file ../../../sources/common/cles.pem master_3_04_dfu_1_00.zip 
 But it returns : 
 Error: Invalid combination: use two .zip packages instead. 
 Do i miss something or it is still not possible to combine the application and the bootloader in one ZIP file ? 
 Best regards, 
 Aurélien

As per the table in the readme for nrfutil, for a combination of Bootloader and Application you'll need 2 zip files. 
 https://github.com/NordicSemiconductor/pc-nrfutil Also make sure you are using the latest version of nrfutil v5.0.0, since you are using SDK 15.3 and SD v6.1.1.
