How to move the head of a track on plan? (PARAM-O)

[Isadora Almeida]

I created this fixture with track and heads with the PARAM-O tool, but I need the heads to be able to also be located manually on plan, does anyone know how to do it?

PARAM-O frustratingly does not allow you to add hotspots. 
You can however add a parameter which would allow you to set the distance of each light in the object tool settings. 

If you desperately need hotspots in 2D you’d have to modify the param-o object gel and all the hotspots that way.  This however will loose the ability to edit the param-o code in the future.
