[NTG-context] Using Nibus Roman with MkIV

Hi, Is it possible to use Nibus Roman with MkIV. I have to send a document where the font used **must** be Times New Roman or Nimbus Roman. I tried using a clone (Termes), but I was told that I must use Times New Roman or Nimbus Roman. (It is a matter of regulations, so it is not possible for me to explain that Termes and Nibmus Roman are essentially the same). So, is it possible to use Nimbus Roman (type1 font) in MkIV? Thanks, Aditya
