Hi, @Sk210-6yq08.
Thank you for adding a post!
Yes, you can update your non-inventory items to inventory. However, have to do it manually through the Product and Services window. I can guide you on how.
- Go to the Gear icon, then select Product and services under Lists.

- Look for the item you want to update, then click on Edit under Action.
- Tap on the Change type link beside Non-inventory.

- Repeat the steps for the rest of the items.
