I would like to see a "Jump" function added to allow one to move forward or backward by a specified duration on a video clip.

Example:
Function: Jump
Value: +30000 ( jump ahead 30 sec)
Input: 0 (for preview, or 1 for PGM)

The value should be able to accept "-30000" if I wanted to jump backwards 30 sec.

I realize this is available as a shortcut using SetPosition, =+30000, however I am using Central Control on an AWS instance, and I when I use SetPosition, this will move to a specified location only. I would like to press the button multiple times, jumping the specified duration on each button press.
Thus, the suggested Jump feature as "Execute Function" with device mapping using Central Control would be much appreciated.

Sincerely, db
