Can you 2 gang 240v receptacles
If it is 15A or 20A, You can have as many 220V outlets as you want, single or double receptacle.   Except you cannot have them in certain rooms of a home.   

You can use 15A receptacles on a 20A circuit, as long as there is more than one receptacle in the circuit. 

So just change this  to this  and done.
