I had a unpleasant surprise when bringing my madmaper file to another computer
on my machine I had donwloaded materials , when I copy the files to the other computer( behind a firewall from an university not able to download from the internet ) I discovered that the materials were missing
is there a way to save any material into the madmaper file

Not at the moment, you can copy the whole folder of materials:
on macOS: /Users/$username$/Documents/MadMapper/Materials
on Windows: C:\Users\$username$\Documents\MadMapper\Materials
