Need the Nb of Multiplexer-16 DataPin increase from 4 to 11 or more on the Arduino Mega

[RamsesTwo]

Hello Guys,
I love the use of the Multiplexer, soo easy and powerfull
The increse with the "Add device" to 4 Multiplexer as 4 DataPin for the Mega was nice... in this Version 9.6.0

My current project is all done for (2) MCDU A320 PCBoard etc.. Using only one Mega + one Mux(74x4067)
Except for the fact that I depend on 11 DataPin in link with the Multiplexer see the image in Ref.

The current version Mobiflight 9.6.0 now deal with only 4 DataPin for the Arduino Mega ...
I tink that it would be so easy for you guys to increase that limit to 11 or more ... I so mutch depend on it ... please .....
What would it take in Donation to have you increase that limit of 4 to 11 (my need) or more ???
Hope to ear from you Guys soon ...
