Transferring a file to multiple remote desktop connections in one go

Using the Remote Desktop Manager, is it currently possible to transfer a file from the host PC to multiple open RDP connections in one go?

To transfer a file, I currently have to copy the file from the Host PC and then go to each of my open RDP tabs in the Remote Desktop Manager and pasting the file in each of the connections, but I was wondering if there's a more efficient way of doing this? Ideally one that doesn't involve having to go through each individual connection and manually pasting the file.

Thank you for your time,
