Assign a new item or existing item to all available inventory organizations automatically

Content

Dear Experts,

We have an requirement from an customer to check whether we can auto assign the newly created or existing items to all available Inventory organizations in fusion application?
Lets assume that we have more than 100 odd Inventory Orgs and we would need to check if we can auto assign the items to all 100 odd Inventory Org? Is this supported by PDH?

We assume we can use item rules for assignment with few organizations. But with the count of 100+ organizations, can you please suggest a solution to achieve this requirement?

Thanks,
Vijay
