Adding Yemen Eyalet Uthmani [решено]

Hello! I wonder if it might be possible to add a new issuing authority for Yemen?

It seems there used to be the ability to add coins for the Yemen Eyalet Uthmani (1517-1636) under the Mutawakkilite Kingdom, for example: https://en.numista.com/catalogue/pieces121822.html . However, this option seems now to have disappeared, and it is not possible to add a coin for this currency under either Yemen or the Mutawakkilite Kingdom.

Might it be possible to restore this currency, possibility under 'Yemen' rather than the 'Mutawakkilite Kingdom' (much like Ottoman provincial currencies are available for Iraq, Syria, etc.).

Many thanks for your consideration!
