Microsoft Remote Desktop Client for Mac & Numlock

I was previously using Microsoft Remote Desktop Client 2.1.1 for Mac to access a Thinkpad that I have. I recently updated to the version of Microsoft Remote Desktop Client in the Mac App Store (version 8.0.3).

The problem I am having is that previously I could map keyboard keys for each RDC connection in the setup for that connection. I would map the Mac extended keyboard CLEAR key to NUMLOCK.

However, with the new v8.0.3 client I see no such settings for mapping keys and I cannot seem to get NUMLOCK to function.

Anybody have NUMLOCK working with Microsoft Remote Desktop Client for Mac v8.0.3?
