Not automatically, but it's not difficult to do:

Move the peg to the intersection, then geometry > constant radius.

Repeat for the other track if it's also a transition.

make diamond-crossing

align the main road of each half-diamond over the underlying transition template.

Adjust the V-crossing angle using F9 mouse action on each half-diamond until it best aligns with the underlying templates. Don't change the K-crossing angle.

Not always a perfect fit, but usually close enough in practice. If you want a perfect fit, it's necessary to split out all the crossings onto partial templates, and copy the closure rails from the underlying templates.

regards,

Martin.
