OpenBuildings. How to change duct fitting depending on the size of the duct?

Question

Hello everyone! 
 
 While I draw ducts, sometimes some changes are required and after I modify properties of duct, fittings stay the same. 
 There is a question, is it possible that duct fitting will change automatically after the size of duct is changed? 
 
 Thanks in advance
