OT: Excel logging w/ripple timecode?

We have a project that will need a lot of ADR. The person who will create the ADR script (in Excel) can't start until the cut is locked, because if we make any changes after she's started, her timecode references will be off.

Does anyone know of an excel template (or some other tool) that would allow her to do a draft, and then if we change one or two edits, be able to ripple the timecodes in her spreadsheet?
