To proceed with current enrollment

Summary

Current enrollment will show instead of default value when plan opens for enrollment every year

Content

We have a plan, so according to current configuration when employee enrolled this plan so in every year when the enrollment opens when employee will add grandfather, there will be able to edit the coverage and every year when the enrollment opens the coverage value shows the default value and there the employee again can enter own value what he wants. 

But now the requirement is that for example in 2019, if the employee enters in coverage 20000 and save it, then when in the year 2020 when the enrollment for this plan opens again, then it should not show the default value , it show the current enrollment of the employee for this plan. Is it possible then please suggest.
