Markers and Tempo with Video

Apologies as this is a newbie question, I’ve done some searching but I’m on an unexpected deadline so thought I’d ask you guys for help.

I’m scoring to video, and have several markers placed and SMPTE locked perfectly.

I’m going to need to edit the tempo at nearly every marker, is there a quick way to create a tempo edit point at each marker?

Secondly is it possible to SMPTE lock tempo changes, so that the change point always stays with the marker?

Many thanks.
