The default "Source Type" during creation PR

Summary:

Hello,

I have 2 items: one was created manually and the other was transferred through the migration.

I would appreciate your help on this issue

I am in the process of creating a requirement for an application and encountering an issue related to the default destination type. 

When I enter an item that was created manually, the default "Source Type" is set to "supplier" and works correctly.

However, when I enter a converted item (all items are tagged similarly except for the converted item), the default "Source Type" is set to "inventory" instead of "supplier", and the user has to manually change it.
