Help for Aimeos

I have the following categories in my shop:

1.Wheels
2.Modeling
3.Clothes
4Electronics

each of them needs a different mapping in order to import their own csv, but, as far as I know, I could only make 1 type of mapping in the shop.php.
What should I do?

Hi, how am I supposed to make a different mapping for each category? Is it even possible, or will I have to make a new shop for every kind of product?

Hello, I was wondering if it's possible to have more than 1 language for attribute types.

Would this work?
1 => 'attribute.type',
2 => 'attribute.type.language',
