Copy hotspots from V3 to V4 ?

[soulbrother]

Hi,

is there any way to copy (all) hotspots from a .p2vr project file (v3, one project file out of many associated of one tour)
into a v4 project file (to the selected pano)?

As I often used hs for text-fields, external loaders, special functions and so on, so there are sometimes many lines written inside a hs, so it would be an enormous time-saver, if there is way to do that.

Any known way?

Thanks a lot!
