Entering & sending MIDI sysex with Waveform?

[dynamo]

Is it possible to enter (type in from the computer) and then send MIDI Sysex strings from Waveform? I'm on a Mac and haven't found any software that will do this (only send contents of Sysex files), but thought I'd ask here since Waveform supports MIDI.
I've had a look at the MIDI panel but haven't had any success so far.

I'm using Waveform Pro 11.1.0 on a Mac running MacOS 10.13.6 (High Sierra).
