Add glide portamento parameters into Sfizz itself

[audio2000]

Was wondering if anyone would be willing to add glide / portamento / legato parameter into Sfizz itself.
I have seen many people use different terms for this, I would call this "GLIDE" if added, but I am referring to where a parameter is provided to set MIDI note output to mono (only one note at a time) and then when MIDI notes are overlapped (both held down at same time the notes glide into each other. The glide time/length can be set with an amount parameter knob. Again if added I would just label this knob "GLIDE" as shown in example below.

I am using Linux at the moment, but a Windows based SFZ plugin example can be seen here with such parameters built into the GUI, so it is possible. (Upper right hand corner of plugin)

I have seen it mentioned that Sfizz kind of has a way to achieve this using CC140 but I unfortunately do not understand this because typically MIDI software/controllers only go from 0-127CC.
Also if this is done, I do not think the paramter knobs would appear in Sfizz GUI itself, unless I am incorrect? Still would be nice if could be built in.

Thank You
