How to configure 600 categories using item rule set Assignments for an item

Summary:
I have created a rule set for 6 categories where its return a value and assign it to an standard attribute defined under Inventory —> Default Expenditure Type.
Its working fine as expected shown in snip.

Now , I have been stuck for about bulk categories where I have 600 categories with corresponding value and I need to setup in system which automatically do the same for all 600 categories.

Is it possible to achieve this using item rule set or lookup solution?
