I dont think so. This is design. If you look at the standard code you will see that after the main FM call to create/update material master, the logs are simply written to SLG1.
Personally I think this is correct in this case as there will be a lot of messages raised. Each of these messages cannot/should not be written as a status record to the idoc.
You could write a separate program that can read the status record of the idoc to find the corresponding SLG1 transaction id and read data from the same and display as report output if required.
