Tempo track curiosities

[winkpain]

I am liking the Tempo Track addition! Couple questions, 'tho:

Is there currently a toggle setting somewhere to select tempo changes with clip (for copies or moves) such as there are with envelopes and articulations?

This can be done with a "Copy/Paste Special...", I know, but curious if there is a quick toggle option to lock/associate tempos to clips.

and

Is there a way to select multiple tempo changes and collectively alter their curve type to a preferred one? Or a way to set the default curve to something other than Jump?
