How to convert a Mark up to a part in Composer?

Hi ,

I am trying to attach a link to an arrow( Mark up). Is there anyway I can convert a Mark up to a part so I can link it to an animation.

I tried capturing the image of the arrow but it is 2D and I need a 3D  object that moves with  the part if someone rotates it.

Please see the attached file

Thanks
