is it possible to install a switch here?

Hi, in the diagram there is a white switch responsible for the LED display sequence, is it possible to install a second switch responsible for another sequence so that it matches the diagram? If not, how can it be done then?

Hi,

Nobody knows .. or better say ... I don't know which signal is for what.
What is input what is output.
Are there current limiting resistors, are there pullup or pulldown resistors..
Usually there are datasheets telling how circuits work and how to connect them properly.

Thus I'd say it's rather impossible to answer your question.

Hopefully there is one that already knows the circuits and their functions.
