Moving requirements arround

Hi,

I know it is possible to move requirements from internal to external. In this case the link is managed in the requirement window as external maked as Yes. Other requirements drawn on custom diagram who are realised by other elements are not shown in the requirement window of this element. Is this the intended behavior? My other question is is there a easy way to change a external requirement into a internal requirement ?
Please help.

I didn't find the right solution from the Internet.
