MRO interim order structure-Automatic Disassembly

In MRO interim order structure, when you RMB on a level of the tree navigator and go to Automatic Disassembly, you have the option 'Include Sub Levels'. This is automatically checked. I do understand it's being automatically checked when you RMB from the header, but when you do so from the navigator I believe it shouldn't be checked automatically as we want to disassemble the MRO SO interdependently
