Question concerning assigning Key to Sustain Pedal [Pianoteq 2.3]

Good day!

To make this short, are we able to assign a key to make for e.g. Sustain Pedal function via Keyboard Keys? not necessarily Keyboard which I'm not willing to use as an alternative pedal press but just as an example because I'm using a fully-working incompatible sustain pedal which is still inconvenient..complicated but it only works as toggle mode using a program keys profiler, although It is not a toggle pedal..it's exactly function identically to Piano Pedal but I have to press it twice to turn on/off sustain pedal which is uncomfortable.

Also I tried assigning the pedal by clicking the pen icon but like I said, pressing key is unresponsive.

I'll appreciate your help!
