VAT reverse charge for purchases from foreign suppliers for VAT exemption

I have a European online supplier where the only option is to make purchases and they reverse the vAT liability to the purchaser. As is also laid down in European regulations. I can’t immediately find a way to enter this as an option for vAT here, nor to generate the file required for the special vAT declaration that comes with this on a quarterly basis.

Can anyone here help me?
