Changing frame Rate

When I create a new project in IstopMotion, i need to set the frame rate project.
If i choose 12, and after some shoot i will want to change the frame rate, can I do that?

Currently this is not possible but there is a workaround:
select all frames and go to file > export selection > as images
Create a new document with the settings you need and then drag the exported images to the timeline of the new document.
