Mass ROU Adjustment

Good Day;

As part of our transition approach, any balance that is currently seating in the normalization/smoothing account needs to be written off against ROU account.

We have read that the way to go about achieving this is to make an adjustment under lease Option tab.

Is there an API to mass update the options tab for the current set leases?

Or how else will we achieve mass adjustment of ROU with Normalization balance?
