Convert Group to Dynamic Permission.

Hi Guys. 

I am trying to delegate the management of Dynamic Groups to a specific team that uses the MMC. 

I have allowed write to the edsaCanBeMadeDynamicGroup and edsaDGConditionsList and this has allowed me to edit existing Dynamic groups and change the membership. What I am unsure of is which attribute is controlling being able to right click a group and convert to Dynamic. 

I don't see anything that jumps out at me.
