No, I had long ago asked for this to be included in the API. I could not remember if I formally made a request, and asked if the internal dB could be checked. I don't think I had gotten any response.
I gave up. They have not added many of our requests to the API in the past 3 years. (They seem to have been concentrating upon the C API,... bringing it up to parity with the current Ruby API.)
The only workaround may be to use a template that has one each of an animation page and a non-animation page. When you want one or the other, you set the current active page to the kind you want. Using a
FrameChangeObserver detect when transition is complete, then create your new scene page. The new one will have all it's properties copied from the active page. (Lastly the active page will be set to the new page, so detect the end of creation again with the FCO.)
