Efficient way to add/replace field values in data container

I am using Jmix 2.1.3.

I am fetching some data from rest endpoints. I need to use some of attributes from these endpoints in list views of my 3 entities. My own tables are fairly large whereas rest data is not large in size, that’s more like reference data. I need to replace and also add a field in my data containers with data coming from rest endpoints to show in list view. What could be an efficient way to achieve this?
