Other applications have add on packs that offer great dedicated ADR functionailty.
Is the replacement dialog in the same language as the original content?
You can kinda sorta use Audio Snap to do crude ADR.
The stuff available for Pro Tools and Nuendo is dedicated to ADR and has lots of solid automation features.
Vocalign is a VST that could work in SONAR, but it's full functionality requires VST3.
Have fun.
