Forcing two same environments to be splitted

[fAX k.root]

Hi!

I have a question. If I want 2 definitions one after other to be 
numbered separately, I don't know how to do this elegantly. For now, I'm 
forced to put an invisible note or make nested environments. How can I 
tell LyX that I want TWO SEPARATE definitions, not ONE MERGED?

Thank you in advance.
