How to export AECOsim building designer or Navigator created name group/Items sets?

Hi, 

I create lots of Item sets in AECOsim then create an animation.

now, I hope can export the information data include scheduled time, group and Items, 

but AECOsim seems didn't have export in item sets group include items, and Navigator is not too.

but the function has import item sets, 

Can anyone help me this question?

Thanks
