Find and replace Trigger Conditions

Hi guys,

I have tons of triggers, conditions and variables in one of my SL360 projects.

I have to copy-edit lots of conditions. I edit manually ie change variable assignment in the dropdown menu (see screenshot). Ex. Replace Q02 > Q03 x 50. 

Is there any ways to search-replace, or to externalize this using javascript, or to edit source code after publishing?

Thanks for your help and advices!
