Starting point

[Giochia]

I am trying to use this library to slow down robot arm, because the fast speed could destroy servo gear coupling, due to inertia force.
The problem is that the library sets the motor starting point to 90 degrees only, and I cannot seem to be able to change this. Since my starting point, for the arm at resting position is a different value (20 degrees) the system results in giving a jerk to set the 90 degrees before starting positioning, and this is a problem.
Can we have a possibility to set a different starting point ?
