You cannot do that currently.
Please edit all your camera animations before the show.

But I need this functionality So are there any suggestions for doing such task?

this feature is very helpful for studio operators and if there some kind of switching mechanism between the two animation so we don't have only cut transation between preview and program outputs. 

You are using a fixed physical camera serving as your billboard's feed, and your billboards' positions are fixed in the virtual space. In your case with the current workflow in Aximmetry the best approach is to plan the virtual camera paths before the start of your live show.

If you really need this feature and want to edit the virtual camera paths and transitions during the live show, it is possible. With our current version of Aximmetry this would require a multi-machine setup and a separate video mixer.

Thank you for your insight. We will consider it!
