I haven't found any way to set the custom refresh image. Now, I have done something different on my Nextbook Windows Tablet, but I don't know if it would actually work or not. It came with Windows 8.1 with Bing installed. I know it is next to impossible to download a standard Windows 8.1 with Bing install ISO so the first thing I did was create an image of the complete 32 GB memory using Macrium Reflect to restore in case Windows 10 failed. Then I did a clean install of Windows 10, which read the product key stored in Bios for Windows 8.1 for activation.
That created the EFI boot partition, the 128mb empty space, OS partition and Recovery partition - which contained only the WindowsRE environment. I made the WindowsRE files readable by doing attrib -h -s on them. Copied them to the SD card. Deleted the recovery partition, shrunk the C: drive partition and moved it to the end of the "disk". Deleted the 128mb empty space. Expanded the EFI boot partition to about 5gb in size.
Then I copied the Windows 10 WindowsRE files to the EFI boot partition and copied the install.wim file for the factory Windows 8.1 from my backup image to the EFI boot partition. Then I set the reagentc OSImage and WindowsRE pointers to the correct folders in my combined EFI Boot and Recovery partition and enabled reagentc.
I know the WindowsRE environment works because that is easy to test. In theory, if I select the reset option from the recovery menu, I should get the factory Windows 8.1 with Bing restored. Haven't tested that yet (I still have my Macrium Reflect image backup). If I want to "reset" Windows 10, I can just an in-place upgrade repair install of my Windows 10 install USB.
