ESU LokPilot decoder - how to remap function keys

[Thommo]

Hello,

I've bought used/as new Roco locomotive with ESU LokPilot decoder in it, seller is almost certain it is v3.0 version. I woud like to re-map front and rear function keys, to works like this:

F0 - head lights on/off
F1 - rear lights on/off

I do not want to have lights go on and off by direction of travel.

I have few TCS decoders, this above was a matter of two CV's changed - and voila. I am sure ESU decoders have this functions as well, but maybe someone has allready tried this?

Thanks!
