Can expenditure type be used to restrict PPM Cost Transfers?

Summary:

In our organization there are certain expenditure types that can only be used in certain project types (example the expenditure type 533000 - First 25K of Subcontract Services can only be used for sponsored projects). We have discovered that financial managers are using the PPM Cost Transfer to move costs with certain expenditure type to project types that do not allow for this kind of expenditures. Is there a way to stop Financial Manager from using the PPM Cost Transfer for a specific expenditure type?

Example:

An invoice for 2,000 was processed using expenditure type 533000 - First 25K of Subcontract Services and charged to a sponsored project NSF1234567. Now the Financial Manager using the option PPM Cost Transfer tries to transfer the charge to an internal project. Would like to see if it is possible to block the use of the PPM Cost Transfer for transactions with expenditure type 533000 - First 25K of Subcontract Services.
