image sequence frame rate is not converted when exported with a different framerate than the project settings.

When I create a project with 12fps and I import an image sequence it gets the framerate of the project. But when I export the project with a different profile that has a framerate of 25fps, the image sequence doesn't get scaled to 25fps but instead plays repeatedly to fill up the space it occupies in the timeline. Although I can understand that this behaviour follows some logic, it is not what I had expected.
I would suggest that Imagesequences should have a framerate setting under properties, to avoid confusion and increase flexibility.
