Currently not possible in BIMx - it would certainly be a great improvement for the software though. You might want to look into Twinmotion. It doesn't allow display of BIM information like BIMx does, however is more suitable for lighting, vegetation and in general visualization. Let me know if you need more help about this.

As Emre mentioned, currently it is not yet possible to do so. Fortunately, I found that we already had a similar wish in our Wish List database (please refer to it as #8226). Hopefully we will be able to implement it in a future version of BIMx soon!
