Enrollment Loader - Upload only original enrollment date?

Summary

We need to update the original enrollment date for 2019

Content

Some of our vendors need to have the enrollment date as the date in which the participant enrolled in the plan/option combination. 

We know that with life events that are set up at the program level it updates the coverage start date every time regardless if a change is being made.

1) Is there a way to prevent the coverage start date from updating if the elections are not changed?

2) Since we believe we need to utilize the original enrollment date as this is a static date if no changes are made, is there an option to just upload this data rather than reopening the entire event and loading benefits?
