Request: LAST_TOUCHED_FX_PARAM_NUMBER

[AlbertoV5]

Hello. This is the current last touched fx section:

LAST_TOUCHED_FX_TRACK_NAME s/fx/last_touched/track/name
LAST_TOUCHED_FX_TRACK_NUMBER s/fx/last_touched/track/number/str
LAST_TOUCHED_FX_NAME s/fx/last_touched/name
LAST_TOUCHED_FX_NUMBER s/fx/last_touched/number/str
LAST_TOUCHED_FX_PARAM_NAME s/fxparam/last_touched/name
LAST_TOUCHED_FX_PARAM_VALUE n/fxparam/last_touched/value s/fxparam/last_touched/value/str

This is the existing FX number message:
LAST_TOUCHED_FX_NUMBER s/fx/last_touched/number/str

This is what the section is missing:
LAST_TOUCHED_FX_PARAM_NUMBER s/fxparam/last_touched/number/str

This would allow the controller to access the second to last touched parameter by index, assuming that the focused fx remains the same, with this message:

FX_PARAM_VALUE n/fxparam/@/value

This stops me from finishing an XY last touched control:

It all works, the code stores the last_touched values correctly, I am just missing the message to obtain the index of the second to last touched parameter (which is what I am asking about). The axes "rotate" every time a new fx param is touched, so X is the future last touched by default. They reset once "fx/last_touched/name" changes which means the focused FX changed.

----

So, is it possible to index the last touched fx param on the focused fx? If so, can the message be implemented, is it worth it?

Thanks.
