Overriding Resources

Hi,

I have tried to overwrite resources for the FR945 due to a change in fonts I have setup a file which controls how big the font is via some variables. I have this file for the FR945 and for other units. But I have no clue what I have to specifiy in the jungle file. Here a fenix5 string is mentioned:

but what do I have to state in the jungle file if I wnat to apply an .mc file for the FR945 and what do I have to state for all other watches. Pretty confusing....
