Multiple Domains for Single Market (E.g Dutch Speaking Market: .nl Netherlands and .be Belgium)

[faecom1]

Hi

in Primary market i can Enter multiple domains but i want only one domain in Primary market and multiple domains (.be, .at, .fr and so on) in eu market but i dont have the Button to add multiple domains in the EU Market.

Primary market Settings:

but in the EU Market i am only able to Insert one separate domain. 

EU Market Settings:

Any advice to solve this issue without separating each country into a new market. 

If this isn't possible i'd like to request this feature.
