Vmb2bl & raffstores

I’m using the blind control vmb2bl, to handle my raffstores
warema.de/de/Produkte/Raffst … _Index.asp

it works ok, but I have a small issue controlling the “leveling” of the blades.
a short press results in a automatic up or down move for the configured time (30sec - 60 sec) … but I would need a short press of
0.5 -> 1.5 seconds to adjust the light interval.

Can I somehow overrule this “hold down/up”’ command. Or that it start only when pressing for 3 seconds …
Currently I’m handling it by short press up and down so that the down command stops the up command, but it’s not really easy.
I’m planning to create a software program for “fine” adjustments.
