What are the best practices for using sequence in a Position EFF

Summary:

We have a requirement to track 'Product' values against a position, and part of the requirement was that there could be one position supporting many products, so we decided to use a multi row EFF on the position. Our finance team will maintain these products on the position from outside of HCM using HSDL. When loading the HSDL, sequence must be provided as we're unable to provide a sourcekey using HSDL. The sequence concept will be confusing for the finance business users, hoping to simplify, but need feedback on our current direction.
