[TYPO3-english] Import .t3d without extensions

[ktt]

Hello,

I exported once the site with extensions, but now I can't find one them in repository - searchajaxgoogle. And there is no option to exclude extensions while importing .t3d.
Are there any methods to solve this situation? I think would be wise and logical to make checkbox excluding/including extensions from t3d in TYPO3 panel.

Regards,
Ktt
