[QGIS-Developer] QGIS 3.4 preconfigured algorithm ?

[FERRATON Alain (Chef de groupe) - SG/SPSSI/CPII/DOO/ET]

Hello,

I put my request on the qgis-user list without success.
So I'm taking my chances on the developer list.

I can't find the possibility to make 'preconfigured algorithms' with 
QGIS 3.4?

Has this feature been removed?

how to do it?

regards,
