Point the locators of an item for stockman - Changing Locator LOV

 Hello,

I have a business rule is that is to help the stockman so that he can know where the item is stocked (point the locators of each item). The are so many items for him remember each locator where each item is stored, and each item is stocked in varios locators in the warehouse/subinventory.

To attend this requirement, the idea is in locator field of each inventory transaction, restrict the locator LOV so that will be able to show only the locators where them are stored, based on Item/Subinventories screen.

I've tried Forms personaliztion but I can't find the LOV for Locator field in the forms.
