Generating two ID on linux

Hi there
So im running Linux Mint 19.3 and i want to be able to trade pokemons with myself
I have both Citra and Citra Nightly installed but apparently both have the same ID
I can find the directory in Citra but not on Citra Nightly
By right clicking on Citra i can “Open Directory Location” but not so much on Nightly
With some research i found that copying files from one to the other you are able to change ID afterwards
So does anyone know how to manage this on linux?
is there any other way than the one people are suggesting?

Thanks in advance!
