BmInsert: How to use the Rotate option?

I am trying to use the Rotate option of the bmInsert (and -bmInsert) command. There must be something that I am doing wrong, because when I select 'Rotate' I can specify the rotation angle but not the insertion point. The component 'lands' wherever the cursor happens to be located. I have tried to use the Tab key to switch input fields but that is not possible in this case and switching off Dynamic Input has no effect.

What is the correct procedure here?
