How to import Texture Pack Spritesheet into construct 2 ?

Hi,

I'm developping a game for construct 2,

My game contains lots of sprite and animations,

To reduce the memory I have made some spritesheets,

I discovered the software "TexturePacker"

but I want to use the trim mode (wich optimize spaces between sprites), with this mode I can divide by two the weight of my spritesheet wich is very interesting.

so, is there a way to import Spritesheets with Trim mode ?

Thanks for answers !
