Import geometry from graphics with transitions - Delete Multiple Elements

Hi,

I had imported a Horizontal geometry graphically with transitions using Import -> geometry wizard in power rail track. The transitions are added as bits of straight lines. I had also tried checking the box "All selected elements added to single Alignment" option. The entire element gets imported on selecting the alignment poly line. The transitons are imported as pieces of straight lines. And its taking lot of time to delete each unwanted element. Is there any easy way either to import the geometry properly ( transitions as transitions), or import only the straights and curves and ignore transition portions, or delete multiple elements together.
