Hello @noovo
Matrixify app sure can bulk import and export new Metafield types.
The best way to do that is to set up Metafield definitions in your Shopify ADmin → Settings → Metafields.
Then apply values in those metafields for any one product and export your Products with Basic Columns and Metafields using Matrixify app.
In the exported file, you will see Metafield columns for the defined metafields with the new metafield types.
Here in our documentation, you can also see each possible Metafield type listed - https://matrixify.app/documentation/metafields/#MetafieldTypes
