Config. Package Fields Page Not including Blob Field

I am trying to migrate data from my client's existing system into nav 2016. I am running into an issue where I added a blob field to a table and now the field is not showing up on the Config. Package Fields page. I would like to be able to import this through the tools provided.

First question, can I export/import blob fields through the RapidStart tools?

Second question, if first is no, what is the best pracatice? Should I go through SQL Server?

Thank you,
