The same as you would do for single edit (not add - update).
I can give you a specific use case that we were looking for multiple edit to do.
This is for an Electric Utility - Vegetation Management. They contract out the Tree Trimming part to external vendor. The vendor will charge the Utility based on individual lines rate (based on Trim Type). However, the trim type is very complicated and based on combination of 5 different fields - Unit (line or brush clearing), Class (Mechanical, Bucket, etc.), side (for example, 1 side or both sides) Chip vs. No chip, etc. Moreover, the values they will enter for a later field will be based on the former value the had selected. For example, If they select Brush clearing, there is no chip or no chip option. So we will hide that field.
Before the start trimming for the year, the Utility employee (usually a Forester) will select existing line and enter these values in 5 different fields to come up with a rate for that line. Now, if a Forester select 1 line at a time and enter these 5 fields, it will take him/her way longer time than if he/she has the opportunity to select multiple.
