Can I file a different pdf document for each investment fund in the group under the same filing number if the document type is the same?

Yes. To file a different document for each fund in the group under the same filing number you need to create the filing and upload the document for one investment fund in the group. After submitting the filing, search for that created filing, click on ‘Actions,’ click ‘Maintain <document name>,’ and then upload the second document for the second investment fund. Repeat this process until all the documents have been uploaded against the same filing for each respective investment fund in the group. 

This process applies to any continuous disclosure filing, other than MRFP, where you want to submit a different document for each fund under the same filing number when the document type is the same.
