Unable to utilize the mapping set created in Project Financial within the SLA Rule for Inventory P

Issue -

We've created a mapping for the Profit Center segment, which is based on the project-owning organization. Though, this is created in Project Accounting module, I can seamlessly apply this mapping to SLA rules for inventory and other transactions. However, I encounter challenges when applying it to Project Transfer and Manual Cost Adjustment. The created mapping set is not available to be picked in Journal entry rule set.

I also tried to create the mapping in the Cost Accounting SLA for the Intraorganization event type, the available input source only presents a list of Inventory organizations, but not the the Project Owning Organization. Please refer to the attached screenshot for reference.
