Marlin 1.1.9 Mixer Menu on lcd A10M

[ase]

Hi,
I am missing the menu entries to display the mixer settings on the Info Screen and to have the possibility to manipulate it during print with the lcd.

I had problems with bed leveling due an uneven bed (Super Plate) and switched to ubl. But with the Marlin 1.1.8 version ubl crashed into the bed on the far right corner. So I gave 1.1.9/1.1.x a try. I ported everything in the configure.h and configure_adv.h from the original 1.1.8 firmware, added the file pins_GT2560_V3.0.h and added the line to define the file in the boards.h. Compiled it with success (BLTouch enabled) and now ubl works without problems.
Any hints how to port the lcd entries from 1.1.8 to 1.1.9 or has anyone an already ported version?
