Is there any way to use -useLegacyAOT option in FlashBuilder 4.6?

[kemalsen]

I need to build my ipa with old version of Engine because i have some problems about loading images from outside. Since with Air 15 it is default engine, and i cannot quit Air 15 because of the iTunes specs. I cannot add -useLegacyAOT=yes to compiler options on Adobe Flash Builder 4.6 because it seems that it can be added at FB4.7.

So is there any way to add this options when i am using FB4.6

Thanks in advance.
