sliders in Tasker actions difficult to control

Could the sliders (SeekBars) used by Tasker actions be improve or made customizable in settings? I find it impossible to use the press-and-drag method -- they just don't move, and the click method is very hit-and-miss.  Using the arrows is often impracticable when the value range is large since the arrows change the value by only +/-1.  Also in some cases a "logarithmic" (actually "exponential") scale would be more appropriate, e.g. for setting a Beep tone frequency where getting somthing in the middle of the audio spectrum on a linear scale that goes from ~0 to 16000 is extremely awkward.  Or a simpler solution might be to include a keyboard edit box by clicking on the value.
