Is there an easy way to match and import attributes?

I only have one attribute, but I'm having a lot of trouble. Maybe I'm missing some important step that might make this easier.

The attribute is for engravable text.

I have about 15,000 items on my site and about 1000 of them have this attribute.
I can't do matching manually for this many items.

At the matching page, QBI lists items like
EngravableItem1:Text
EngravableItem2:Text
EngravableItem3:Text
...etc

In QuickBooks I just have one service item called EngraveService.

Is it possible to just import the Text attribute as a separate item matched to the EngraveService item in QB?

The way this is importing right now is QBI is automatically creating hundreds of sub-items in quickbooks, this is creating a big mess.

Or if not possible to import the attribute as a separate item, can QBI just match to the item number without creating a sub-item?
For example, currently QBI does something like this
Engravable1:Text
Is imported in QB as
Engravable1
- variable subitem with text input


More appropriate behavior would be to just match Engravable1:Text to Engravable1. No creating sub-items, just include the attribute as the item description.


Thanks.
