The premium add-on has this functionality.

Ok, thank you.
The license is one time payment?

Yip, one time only ??

Ok, thank you very much

Is asking for a solution without paying non ethical or forbidden?

(its for a school project so i wont pay any cents for this, even if i will as soon as i ll need it for myself or a real project)

Thx a lot.
