Mapping option for using analog sticks to control mouse

[Ape]

Trackpad works greatly as a mouse, but in some situations I would like to use an analog stick as a mouse.

Currently, this can be done using either of these mappings:
REL_X = left_analog_x
ABS_X = left_analog_x

However, they control the cursor only when I move the analog stick. I would like to have a mapping option that continuously moves mouse when I am holding an analog stick outside the center.
